2022-08-02math/p5-Math-BigInt: reset PKGREVISION after updateast1-2/+1
2022-08-02PR category/123ast2-6/+6
math/p5-Math-BigInt: update to 1.999837 (from 1.999827) * Improve compatibility with older versions of the Math-BigRat distribution. * Re-enable upgrading in Math::BigFloat->bdiv(). * Improvements to upgrading, downgrading, and rounding: . Fix bug related to upgrading in Math::BigInt->brsft() in Perl <= 5.16. . Fix Math::BigFloat->bpi(). . Improve as_int(), as_float(), and as_rat(). * Improve methods div_scale() and round_mode() so they work better with subclasses. This fixes CPAN RT #125430. * Make div_scale() accept a Math::Big(Int|Float|Rat) object as input. This fixes CPAN RT #140599. * Add new methods numerator(), denominator(), and fparts(). * Fix bug in to_ieee754(). Avoid that the significand overflows.

2021-09-30Update to 1.999825wen2-8/+7
Upstream changes: 1.999825 2021-09-28 * Make Math::BigInt accept integers regardless of whether they are written as decimal, binary, octal, or hexadecimal integers or decimal, binary, octal, or hexadecimal floating point number. * When numeric constants are overloaded (with the ":constant" option) in Math::BigInt, every numeric constant that represent an integer is converted to an object regardless of how it is written. All finite non-integers are converted to a NaN. * When numeric constants are overloaded (with the ":constant" option) in Math::BigFloat, every numeric constant is converted to an object regardless of how it is written. * Add method from_dec() (cf. from_bin(), from_oct(), and from_hex()). It is like new() except that it does not accept anything but a string representing a finite decimal number. 1.999824 2021-09-20 * Don't allow mixing math libraries. Use the first backend math library that is successfully loaded, and ignore any further attempts at loading a different backend library. This is a solution to the re-occurring problem of using objects using different math libraries. * Add missing documentation. * Miscellaneous minor improvements. 1.999823 2021-07-12 * Improve the handling of the backend libraries. Provide more useful warnings and error messages. Update the documentation. 1.999822 2021-07-09 * Make the from_hex(), from_oct(), and from_bin() methods consistent with CORE::oct(), which does not require a leading "0" before the letter ("x", "o", or "b"). * Make the from_oct() and new() methods accept octal numbers with prefix "0o", "0O", "o" (lowercase letter o), and "O" (capital letter O). * Make the from_bin() and new() methods accept binary numbers with prefix "0b", "0B", "b", and "B". * Make the from_hex() and new() methods accept hexadecimal numbers with prefix "0x", "0X", "x", and "X". * Update test files to match with the above. 1.999821 2021-07-06 * Make new() and from_hex() accept the "0X" prefix, not just the "0x" prefix, but not accept just "X" or "x". Now, "0XFF" returns 255, not NaN. * Make new() and from_bin() accept the "0B" prefix, not just the "0b" prefix, but not accept just "B" or "b". Now, "0B1111" returns 255, not NaN. * Make new() and from_oct() accept the "0o" and "0O" prefixes, but not accept just "O" (capital letter O) or "o" (lowercase letter o). Now, "0o377" and "0O377" return 255, not NaN. Also intepret floating point numbers with a leading zero and a binary exponent as an octal number, so that "01.4p0" returns 1.5, not NaN. There is still no ambiguety, since decimal floating point numbers use "e" or "E" before the exponent, and binary and hexadecimal floating point numbers use a "0b"/"0B" or "0x"/"0x" prefix, respectively. 1.999820 2021-07-06 * Fix bug and improve error messages in Math::BigInt::import(). 1.999819 2021-07-02 * Add method btfac() (triple factorial) and bmfac() (multi-factorial), including tests and documentation. * Add missing and correct erroneous documentation for bfac() (factorial) and bdfac() (double factorial). Also correct handling of special cases and add tests for these cases. * Fix error in bsin() and bcos() causing them to hang indefinitely if the invocand is +/-inf. * Make it possible for the end user to specify the base length used internally in Math::BigInt::Calc.
2021-05-24*: recursive bump for perl 5.34wiz1-1/+2
2020-09-07p5-Math-BigInt: update to 1.999818.wiz2-8/+7
* Fix CPAN RT #130736 regarding numify() on a Math::BigFloat with a large number of digits and an equally large, but negative, exponent. * Fix a problem in to_ieee754() due to rounding in bpow(). 1.999817 2019-10-11 * Avoid non-integers in intermediate computations in Math::BigInt::Calc. This causes errors due to rounding issues, e.g., 47265625999999999 / 1000000000 is 47265626 with double precision. * Remove api_version() and the corresponding test file. There is no need to check which methods are supported by a backend library now that each backend library is a subclass of Math::BigInt::Lib. Methods not provided in the backend library are provided by the parent class. * Add to_ieee745() and from_ieee754(). * Add backermann() and ackermann() for the Ackermann function. * Add buparrow() and uparrow() for Knuth's up-arrow notation. * Add information about the github repository. * Update links in SUPPORT section in POD. * Fix bpow(). It returned NaN when it should truncate to zero. * Make blsft() in Math::BigInt allow bases up until the largest unsigned integer. * Make _lsft() in Math::BigInt::Calc handle an arbitrarily large base. * Add new methods bdigitsum() and digitsum() to Math::BigInt. Add new method _digitsum() to Math::BigInt::Lib. * Add new methods is_non_negative() and is_non_positive(). * Extend the default collation sequence used by to_base() and from_base() to all the 94 printable ASCII characters except blank/space. * Make new() in Math::BigFloat handle octal floating point numbers. * Slightly more robust t/01load.t. * Remove unused variables. * Miscellaneous code cleanup.
2020-08-31*: bump PKGREVISION for perl-5.32.wiz1-2/+2
2019-08-11Bump PKGREVISIONs for perl 5.30.0wiz1-1/+2
2019-06-30Update packages using a search.cpan.org HOMEPAGE to metacpan.org.nia1-2/+2
The former now redirects to the latter. This covers the most simple cases where http://search.cpan.org/dist/name can be changed to https://metacpan.org/release/name. Reviewed by hand to hopefully make sure no unwanted changes sneak in.
2019-01-12Update to 1.999816wen2-7/+7
Upstream changes: 1.999816 2018-10-26 * bnok() for Math::BigInt and Math::BigFloat now support the full Kronenburg extension. The behaviour is identical to the behaviour of the Maple and Mathematica function for negative integers n, k. Add tests. This closes CPAN RT #95628. * Fix POD errors. This closes CPAN RT #125141.
2018-10-20Update to 1.999815wen2-8/+7
Upstream changes: 1.999815 2018-10-19 * Move bitwise operators signed and, signed or, and signed xor from lib/Math/BigInt/CalcEmu.pm into lib/Math/BigInt/Lib.pm. The file lib/Math/BigInt/CalcEmu.pm is no longer needed and thus removed. 1.999814 2018-10-01 * Add to_base() and from_base() to Math::BigInt and corresponding library methods _to_base() and _from_base() to Math::BigInt::Lib. This was inspired by CPAN RT #122681. * Fix Makefile.PL to reflect that Test::More is only needed for testing, not for building. * In the documentation for each of the to_(bin|hex|oct|bytes) methods, add a reference to the corresponding from_(bin|hex|oct|bytes) method.

2018-05-02p5-Math-BigInt: update to 1.999813.wiz2-8/+7
1.999813 2018-04-18 * Fix CPAN RT #125108. Remove test files try.pl, t/author-bpi-big-mbf.t, and t/release-unused-vars.t, which were included in the 1.999812 distribution by accident. 1.999812 2018-04-17 * Fix CPAN RT #120351 regarding bpow(). Add test. * Fix CPAN RT #120717 regarding tests now that '.' is not in @INC by default. * Fix CPAN RT #122756 regarding testing for 64 bit integer support. * Fix case when both accuracy and precision are set, resulting in a NaN. This closes CPAN RT #124790. * Fix typo in one of the change log entries for version 1.999811. * Clearify documentation of rounding modes. * Update the documentation of configuration parameters. * Fix rounding and accuracy in bpi(). Extra digits in intermediate computation were not used, causing the last digits to be inaccurate. In addition, the rounding was incorrect in some cases. * Use config() as a method, rather than a function. Also use config("xyz") rather than config()->{xyz}. * Correct more of the problems with rounding in the constructors. If rounding arguments are given as arguments to the constructor, the constructor should assign those values to the instance. If no rounding arguments are given, and the constructor is called as a class method, the class rounding variables should be assigned to the instance. Added test file t/author-constructors-a-p-r.t to replace t/author-constructors-a-p.t, but lots of tests are failing and (for now) commented out. * Remove statements used for debugging. * Fix typos. * Cleaner log/exp-related code in Math::BigFloat. * Remove unused variables. * Add test file t/release-portability.t. * Add test file t/release-whitespaces.t. * Convert test file t/02pod.t to t/release-pod.t and t/03podcov.t to t/release-pod-coverage.t. * Reformat CHANGES to match the specification in CPAN::Changes::Spec and CPAN::Meta::Spec. * Expand tabs to spaces and clean up whitepace. * Include tests that were previously commented out. * Use $LIB as the variable name for backend math library. * Import "carp" and "croak" from the Carp module. * Math::BigInt isa Exporter, so Math::BigInt should require Exporter. Math::BigFloat has Math::BigInt in @ISA, so it doesn't need to require Exporter. * Don't load Test::More when it isn't really needed. This speeds up processing of author test files when they are skipped.
2017-06-05Recursive revbump from lang/perl5 5.26.0ryoon1-1/+2
2017-05-13Update to 1.999811wen2-7/+7
Upstream changes: 2017-03-15 v1.999811 pjacklam * Fix an old in the Math::BigFloat methods as_hex(), as_oct(), and as_bin() methods resulting in loss of accuracy. This bug was introduced in bug in Math-BigInt-1.76. Due to a naive copy and paste by me, and lack of tests, this bug was also present in the newer to_hex(), to_oct(), and to_bin() methods. This shows the bug, as it did not print "0xffff...": print Math::BigFloat -> from_hex("f" x 30) -> as_hex(); * Fix incorrect formatting in the output from the Math::BigFloat methods to_hex(), to_oct(), and to_bin() when the output was zero. A prefix was added when it shouldn't have been. * Add tests to bigintpm.inc and bigfltpm.inc for better testing of as_hex(), as_oct(), and as_bin() as well as to_hex(), to_oct(), and to_bin(). * "Synchronize" tests and code formatting in bigintpm.inc and bigfltpm.inc. 2017-03-01 v1.999810 pjacklam * CPAN RT #120240 revealed that the problems with undefined values is still present. After a close examination, I believe the only way to get this really working is to to make blog() call objectify() differently depending on whether the base for the logarithm is undefined or not. That way we can avoid objectify() converting the undefined value to a zero. Ideally, we should warn about undefined values when used in any other context, but we'll handle that in a later release. See also the related changelog entry for v1.999801. * Fix the way the argument count is computed in objectify(). When an argument count of 0 is given, it means that we should objectify all input arguments. However, it turned out that the actual argument count was computed incorrectly. * Fix CPAN RT #120242 rearding c3 method resolution.
2017-02-11Updated math/p5-Math-BigInt to 1.999809mef2-7/+7
--------------------------------------- 2017-02-10 v1.999809 pjacklam * When a new method is added to Math::BigInt or Math::BigFloat, and this new method requires a new backend library method, die with a suitable error message if the installed backend library does not support this new method. The error message says that the method requires a newer version of the backend library. * Fix typos in Math::BigFloat and Math::BigInt. * Add bfib() and blucas() to Math::BigInt. They return Fibonacci and Lucas numbers, respectively. The actual computation of the numbers is done by the backend library. Documented both methods in POD. Add test files bfib-mbi.t and blucas-mbi.t. * Add _fib() and _lucas() to Math::BigInt::Lib. They return Fibonacci and Lucas numbers, respectively. Document both methods in POD. Add test files author-lib-arithmetic-unary-_fib.t and author-lib-arithmetic-unary-_lucas.t.
2017-01-18Update to 1.999808wen2-7/+7
Upstream changes: 2017-01-11 v1.999808 pjacklam * In Math::BigInt and Math::BigFloat, add methods bdfac() for double factorial. Add tests for this method. * In Math::BigInt and Math::BigFloat, add methods to_hex(), to_oct(), and to_bin() for hexadecimal, octal, and binary string output without prefix. Even for Math::BigFloat there is still only support for integer output. Add tests for these methods. * Add test for as_oct() corresponding to the old tests for as_hex() and as_bin(). * In Math::BigInt::Lib, add method _dfac() for double factorial. Add corresponding tests. * In Math::BigInt::Lib, fix bug in overloaded "int". * In Math::BigInt::Lib, implement much faster versions of _from_hex(), _from_oct(), and _from_bin(). * In Makefile.PL, improve the wording in the message displayed if some of the installed backend libraries are not a subclass of Math::BigInt::Lib (and hence will not provide * Fix minor bugs in some of the author library test files (t/author-lib*.t). * Allow leading and trailing whitespace in the input to from_hex(), from_oct(), and from_bin(). Add tests to verify. This is a regressions (CPAN RT #119805). 2016-12-23 v1.999807 pjacklam * Add a message to Makefile.PL recommending upgrade if old libraries are installed. This message is more or less equivalent to the one appearing in Math-BigInt up until v1.997. * Improve the documentation (POD) in Math::BigInt::Lib. * Speed up _sqrt() and _root() in Math::BigInt::Lib. * Remove checking for exception cases (cases that would return +Inf, -Inf, or NaN) in Math::BigInt::Lib. It has been documented for a long time that such checking should be done by the caller. * Add library methods _to_bin(), _to_oct(), _to_hex(), which are equivalent to the _as_bin(), _as_oct(), and _as_hex() methods respectively, except that the _to_*() methods don't use a prefix in the output. This removes the need for the frequent removal of the various prefixes. Now each _as_*() method calls the equivalent _to_*() method, adds a prefix, and returns the output. The _to_*() methods are faster than the equivalent _as_*() methods were. * Add author test files for the methods _to_bin(), _to_oct(), and _to_hex(). * Add library method _to_bytes(). The method _as_bytes() would have been called _to_bytes() if I had thought of it earlier. The method _as_bytes() is now just an alias to _to_bytes(). The _to_bytes() method also fixes a bug that was present in the _as_bytes() method. (CPAN RT #119346). * Add author test files for the method _to_bytes(). * Add more tests for library methods _inc() and _dec(). When trying to bring the Math::BigInt::BitVect library back to life I realized that the test suite didn't catch certain errors in _inc() and _dec(). * Die if trying to use as_bytes() or from_bytes() with a backend library that doesn't support the corresponding library methods. * Correct minor errors in the output messages in the test files. * Improve/correct various comments in the source code. * More diagnostic output is displayed by the author test files if the AUTHOR_DEBUGGING environment variable is set. 2016-12-13 v1.999806 pjacklam * Add more logic to Makefile.PL regarding INSTALLDIRS (CPAN RT #119199 and #119225). * In the TODO file, remove stuff that has been implemented. 2016-12-11 v1.999805 pjacklam * Fix Makefile.PL so that this module installs over the core version. * Add more tests for _nok() (binomial coefficient "n over k"). These new tests revealed some problems with some of the backend libraries when _nok() was given very large arguments. * Remove t/Math/BigFloat/#Subclass.pm#, which is an Emacs temporary file included by accident. 2016-12-07 v1.999804 pjacklam * Implement as_bytes(), as requested (CPAN RT 119096). Also implement the inverse conversion from_bytes(). This applies to Math::BigInt only. (Alas, these methods will be inherited from Math::BigInt into Math::BigFloat, Math::BigRat etc. where the methods won't work. Fixing this class relationship is an issue of its own.) * Implement _as_bytes() and _from_bytes() in Math::BigInt::Lib. Preferably, the various backend libraries will implement faster versions of their own. Add author test files for testing these methods thorougly. * Fix from_hex(), from_oct(), and from_bin(). - When called as instance methods, the new value should be assigned to the invocand unless the invocand is read-only (a constant). - When called as instance methods, the assigned value was incorrect, if the invocand was inf or NaN. - Add tests to t/from_hex-mbf.t, t/from_oct-mbf.t, and t/from_bin-mbf.t to confirm the fix. - Add new test files t/from_hex-mbi.t, t/from_oct-mbi.t, and t/from_bin-mbi.t for better testing of these methods with Math::BigInt. * Correct typo in Math/BigInt/Lib.pm (otherise -> otherwise) (CPAN RT 118829). * Add POD coverage testing of Math::BigInt::Lib to t/03podcov.t. 2016-12-03 v1.999803 pjacklam * Remove BENCHMARK file. The information was obsolete. * Use ExtUtils::MakeMaker rather than Module::Install in Makefile.PL * Reorder CHANGES file (this file) so the newest entries appear at the top. * Fix error in test information text in various author test files. * Remove author information in LICENSE file. * Inform that the TODO file is not up to date. 2016-11-28 v1.999802 pjacklam * When bzero(), bone(), binf(), and bnan() are used as constructors, don't check whether the class allows the object to be modified. A constructor isn't modifying any existing object. This applies to both Math::BigInt and Math::BigFloat. * Improve bgcd() and blcm(). This applies to both Math::BigInt and Math::BigFloat.
2016-11-28Update to 1.999801wen2-7/+7
Upstream changes: 2016-11-23 v1.999801 pjacklam * Fix, hopefully once and for all, the longstanding problem of handling undef as an operand to mathematical methods. The only method that accepts undef as an operand is blog(), where the second operand might be undef, as in $x->blog() or $x->blog($b), where $b is undef. The undef signifies that Euler's number should be used as the base. With this fix, we should be able to get Math::BigInt::Lite working again. * Add least common multiple method _lcm() to Math::BigInt::Lib, and add corresponding test file t/author-lib-arithmetic-binary-_lcm.t and test data file t/author-lib-arithmetic-binary-_lcm.dat. * Remove internal function __lcm() which has become redundant now that _lcm() is in the library. * Make it possible to use bgcd() and blcm() as class methods, since other methods can be used as class methods. This applies to both Math::BigInt and Math::BigFloat. * Fix blcm() with negative input. The LCM should always be non-negative. This applies to both Math::BigInt and Math::BigFloat. * Add tests for bgcd() and blcm() in t/bigintpm.t and t/bigfltpm.t. * Fix tests for blcm() assuming that LCM(0,0) should be a NaN. LCM(0,0) is 0 by convention. * Prefer Class->config('option') over Class->config()->{option}. However, this does not seem to be working for all options. It seems that this won't work properly until we move the global variables into the OO interface. * Explicitly specify the library in all test files that are shared between Math-BigInt and the library distributions (FaatCalc, GMP, Pari, ...) with, e.g., "use Math::BigInt only => 'Calc';". This way, it will fail immediately if the specified library can't be loaded rather than using the fallback library.
2016-11-17Update to 1.999800wen2-7/+7
Upstream changes: 2016-11-04 v1.999727 pjacklam * Skip test exceeding the range of VAX floating point number in t/bigintpm.inc (CPAN RT 118468). * Fix typo in lib/Math/BigInt.pm (CPAN RT 118550). 2016-11-15 v1.999800 pjacklam * Upgrade bundled Module::Install from version 1.16 to version 1.17. * Add Math::BigInt::Lib (lib/Math/BigInt/Lib.pm), a parent class for Math::BigInt backend libraries. * Use objects in Math::BigInt::Calc, not just array refs. Also use OO-style, i.e., use $class->_add($x, $y) rather than _add($class, $x, $y). * Not all library methods modify the invocand, so call library methods as, e.g, $x = $LIB->method($x, $y) rather than just $LIB->method($x, $y). * Math::BigInt::Calc is now a subclass of Math::BigInt::Lib. * Add Math::BigInt::Lib::Minimal (t/Math/BigInt/Lib/Minimal.pm) for testing inheritance from Math::BigInt::Lib. * Minor simplification in Math::BigInt::Calc->_str(). * Speed up Math::BigInt::Calc->_root(). * Remove test files that were included in the previous release by accident. * Add more tests and use more verbose output in some tests. * Fix typo in lib/Math/BigFloat.pm * Fix documentation error in lib/Math/Calc.pm * Use Config::Tiny and an .ini file to handle the library specific configuration for the author-lib*.t test files.
