-4.2 ‘numfmt’: Reformat numbers
-==============================
-
-‘numfmt’ reads numbers in various representations and reformats them as
-requested.  The most common usage is converting numbers to/from _human_
-representation (e.g.  ‘4G’ ↦ ‘4,000,000,000’).
-
-     numfmt [OPTION]… [NUMBER]
-
-   ‘numfmt’ converts each NUMBER on the command-line according to the
-specified options (see below).  If no NUMBERs are given, it reads
-numbers from standard input.  ‘numfmt’ can optionally extract numbers
-from specific columns, maintaining proper line padding and alignment.
-
-   An exit status of zero indicates success, and a nonzero value
-indicates failure.
-
-   See ‘--invalid’ for additional information regarding exit status.
-
-4.2.1 General options
----------------------
-
-The program accepts the following options.  Also see *note Common
-options::.
-
-‘--debug’
-     Print (to standard error) warning messages about possible erroneous
-     usage.
-
-‘-d D’
-‘--delimiter=D’
-     Use the character D as input field separator (default: whitespace).
-     _Note_: Using non-default delimiter turns off automatic padding.
-
-‘--field=N’
-     Convert the number in input field N (default: 1).
-
-‘--format=FORMAT’
-     Use printf-style floating FORMAT string.  The FORMAT string must
-     contain one ‘%f’ directive, optionally with ‘'’, ‘-’, ‘0’, or width
-     modifiers.  The ‘'’ modifier will enable ‘--grouping’, the ‘-’
-     modifier will enable left-aligned ‘--padding’ and the width
-     modifier will enable right-aligned ‘--padding’.  The ‘0’ width
-     modifier (without the ‘-’ modifier) will generate leading zeros on
-     the number, up to the specified width.
-
-‘--from=UNIT’
-     Auto-scales input numbers according to UNIT.  See UNITS below.  The
-     default is no scaling, meaning suffixes (e.g.  ‘M’, ‘G’) will
-     trigger an error.
-
-‘--from-unit=N’
-     Specify the input unit size (instead of the default 1).  Use this
-     option when the input numbers represent other units (e.g.  if the
-     input number ‘10’ represents 10 units of 512 bytes, use
-     ‘--from=unit=512’).
-
-‘--grouping’
-     Group digits in output numbers according to the current locale’s
-     grouping rules (e.g _Thousands Separator_ character, commonly ‘.’
-     (dot) or ‘,’ comma).  This option has no effect in ‘POSIX/C’
-     locale.
-
-‘--header[=N]’
-     Print the first N (default: 1) lines without any conversion.
-
-‘--invalid=MODE’
-     The default action on input errors is to exit immediately with
-     status code 2.  ‘--invalid=‘abort’’ explicitly specifies this
-     default mode.  With a MODE of ‘fail’, print a warning for _each_
-     conversion error, and exit with status 2.  With a MODE of ‘warn’,
-     exit with status 0, even in the presence of conversion errors, and
-     with a MODE of ‘ignore’ do not even print diagnostics.
-
-‘--padding=N’
-     Pad the output numbers to N characters, by adding spaces.  If N is
-     a positive number, numbers will be right-aligned.  If N is a
-     negative number, numbers will be left-aligned.  By default, numbers
-     are automatically aligned based on the input line’s width (only
-     with the default delimiter).
-
-‘--round=METHOD’
-     When converting number representations, round the number according
-     to METHOD, which can be ‘up’, ‘down’, ‘from-zero’ (the default),
-     ‘towards-zero’, ‘nearest’.
-
-‘--suffix=SUFFIX’
-     Add ‘SUFFIX’ to the output numbers, and accept optional ‘SUFFIX’ in
-     input numbers.
-
-‘--to=UNIT’
-     Auto-scales output numbers according to UNIT.  See _Units_ below.
-     The default is no scaling, meaning all the digits of the number are
-     printed.
-
-‘--to-unit=N’
-     Specify the output unit size (instead of the default 1).  Use this
-     option when the output numbers represent other units (e.g.  to
-     represent ‘4,000,000’ bytes in blocks of 1KB, use ‘--to=si
-     --to=units=1000’).
-
-4.2.2 Possible UNITs:
----------------------
-
-The following are the possible UNIT options with ‘--from=UNITS’ and
-‘--to=UNITS’:
-
-NONE
-     No scaling is performed.  For input numbers, no suffixes are
-     accepted, and any trailing characters following the number will
-     trigger an error.  For output numbers, all digits of the numbers
-     will be printed.
-
-SI
-     Auto-scale numbers according to the _International System of Units
-     (SI)_ standard.  For input numbers, accept one of the following
-     suffixes.  For output numbers, values larger than 1000 will be
-     rounded, and printed with one of the following suffixes:
-
-          ‘K’  =>  1000^1 = 10^3 (Kilo)
-          ‘M’  =>  1000^2 = 10^6 (Mega)
-          ‘G’  =>  1000^3 = 10^9 (Giga)
-          ‘T’  =>  1000^4 = 10^{12} (Tera)
-          ‘P’  =>  1000^5 = 10^{15} (Peta)
-          ‘E’  =>  1000^6 = 10^{18} (Exa)
-          ‘Z’  =>  1000^7 = 10^{21} (Zetta)
-          ‘Y’  =>  1000^8 = 10^{24} (Yotta)
-
-IEC
-     Auto-scale numbers according to the _International Electronical
-     Commission (IEC)_ standard.  For input numbers, accept one of the
-     following suffixes.  For output numbers, values larger than 1024
-     will be rounded, and printed with one of the following suffixes:
-
-          ‘K’  =>  1024^1 = 2^{10} (Kibi)
-          ‘M’  =>  1024^2 = 2^{20} (Mebi)
-          ‘G’  =>  1024^3 = 2^{30} (Gibi)
-          ‘T’  =>  1024^4 = 2^{40} (Tebi)
-          ‘P’  =>  1024^5 = 2^{50} (Pebi)
-          ‘E’  =>  1024^6 = 2^{60} (Exbi)
-          ‘Z’  =>  1024^7 = 2^{70} (Zebi)
-          ‘Y’  =>  1024^8 = 2^{80} (Yobi)
-
-     The ‘iec’ option uses a single letter suffix (e.g.  ‘G’), which is
-     not fully standard, as the _iec_ standard recommends a two-letter
-     symbol (e.g ‘Gi’) - but in practice, this method common.  Compare
-     with the ‘iec-i’ option.
-
-IEC-I
-     Auto-scale numbers according to the _International Electronical
-     Commission (IEC)_ standard.  For input numbers, accept one of the
-     following suffixes.  For output numbers, values larger than 1024
-     will be rounded, and printed with one of the following suffixes:
-
-          ‘Ki’  =>  1024^1 = 2^{10} (Kibi)
-          ‘Mi’  =>  1024^2 = 2^{20} (Mebi)
-          ‘Gi’  =>  1024^3 = 2^{30} (Gibi)
-          ‘Ti’  =>  1024^4 = 2^{40} (Tebi)
-          ‘Pi’  =>  1024^5 = 2^{50} (Pebi)
-          ‘Ei’  =>  1024^6 = 2^{60} (Exbi)
-          ‘Zi’  =>  1024^7 = 2^{70} (Zebi)
-          ‘Yi’  =>  1024^8 = 2^{80} (Yobi)
-
-     The ‘iec-i’ option uses a two-letter suffix symbol (e.g.  ‘Gi’), as
-     the _iec_ standard recommends, but this is not always common in
-     practice.  Compare with the ‘iec’ option.
-
-AUTO
-     ‘auto’ can only be used with ‘--from’.  With this method, numbers
-     with ‘K’,‘M’,‘G’,‘T’,‘P’,‘E’,‘Z’,‘Y’ suffixes are interpreted as
-     _SI_ values, and numbers with ‘Ki’,
-     ‘Mi’,‘Gi’,‘Ti’,‘Pi’,‘Ei’,‘Zi’,‘Yi’ suffixes are interpreted as
-     _IEC_ values.

+     Use printf-style floating FORMAT string.  The FORMAT string must
+     contain one ‘%f’ directive, optionally with ‘'’, ‘-’, ‘0’, width or
+     precision modifiers.  The ‘'’ modifier will enable ‘--grouping’,
+     the ‘-’ modifier will enable left-aligned ‘--padding’ and the width
+     modifier will enable right-aligned ‘--padding’.  The ‘0’ width
+     modifier (without the ‘-’ modifier) will generate leading zeros on
+     the number, up to the specified width.  A precision specification
+     like ‘%.1f’ will override the precision determined from the input
+     data or set due to ‘--to’ option auto scaling.
+
+‘--from=UNIT’
+     Auto-scales input numbers according to UNIT.  See UNITS below.  The
+     default is no scaling, meaning suffixes (e.g.  ‘M’, ‘G’) will
+     trigger an error.
+
+‘--from-unit=N’
+     Specify the input unit size (instead of the default 1).  Use this
+     option when the input numbers represent other units (e.g.  if the
+     input number ‘10’ represents 10 units of 512 bytes, use
+     ‘--from-unit=512’).  Suffixes are handled as with ‘--from=auto’.
+
+‘--grouping’
+     Group digits in output numbers according to the current locale’s
+     grouping rules (e.g _Thousands Separator_ character, commonly ‘.’
+     (dot) or ‘,’ comma).  This option has no effect in ‘POSIX/C’
+     locale.
+
+‘--header[=N]’
+     Print the first N (default: 1) lines without any conversion.
+
+‘--invalid=MODE’
+     The default action on input errors is to exit immediately with
+     status code 2.  ‘--invalid=‘abort’’ explicitly specifies this
+     default mode.  With a MODE of ‘fail’, print a warning for _each_
+     conversion error, and exit with status 2.  With a MODE of ‘warn’,
+     exit with status 0, even in the presence of conversion errors, and
+     with a MODE of ‘ignore’ do not even print diagnostics.
+
+‘--padding=N’
+     Pad the output numbers to N characters, by adding spaces.  If N is
+     a positive number, numbers will be right-aligned.  If N is a
+     negative number, numbers will be left-aligned.  By default, numbers
+     are automatically aligned based on the input line’s width (only
+     with the default delimiter).
+
+‘--round=METHOD’
+     When converting number representations, round the number according
+     to METHOD, which can be ‘up’, ‘down’, ‘from-zero’ (the default),
+     ‘towards-zero’, ‘nearest’.
+
+‘--suffix=SUFFIX’
+     Add ‘SUFFIX’ to the output numbers, and accept optional ‘SUFFIX’ in
+     input numbers.
+
+‘--to=UNIT’
+     Auto-scales output numbers according to UNIT.  See _Units_ below.
+     The default is no scaling, meaning all the digits of the number are
+     printed.
+
+‘--to-unit=N’
+     Specify the output unit size (instead of the default 1).  Use this
+     option when the output numbers represent other units (e.g.  to
+     represent ‘4,000,000’ bytes in blocks of 1KB, use ‘--to=si
+     --to-unit=1000’).  Suffixes are handled as with ‘--from=auto’.

+----------------------
+
+The following are the possible UNIT options with ‘--from=UNITS’ and
+‘--to=UNITS’:
+
+NONE
+     No scaling is performed.  For input numbers, no suffixes are
+     accepted, and any trailing characters following the number will
+     trigger an error.  For output numbers, all digits of the numbers
+     will be printed.
+
+SI
+     Auto-scale numbers according to the _International System of Units
+     (SI)_ standard.  For input numbers, accept one of the following
+     suffixes.  For output numbers, values larger than 1000 will be
+     rounded, and printed with one of the following suffixes:
+
+          ‘K’  =>  1000^1 = 10^3 (Kilo)
+          ‘M’  =>  1000^2 = 10^6 (Mega)
+          ‘G’  =>  1000^3 = 10^9 (Giga)
+          ‘T’  =>  1000^4 = 10^{12} (Tera)
+          ‘P’  =>  1000^5 = 10^{15} (Peta)
+          ‘E’  =>  1000^6 = 10^{18} (Exa)
+          ‘Z’  =>  1000^7 = 10^{21} (Zetta)
+          ‘Y’  =>  1000^8 = 10^{24} (Yotta)
+
+IEC
+     Auto-scale numbers according to the _International Electrotechnical
+     Commission (IEC)_ standard.  For input numbers, accept one of the
+     following suffixes.  For output numbers, values larger than 1024
+     will be rounded, and printed with one of the following suffixes:
+
+          ‘K’  =>  1024^1 = 2^{10} (Kibi)
+          ‘M’  =>  1024^2 = 2^{20} (Mebi)
+          ‘G’  =>  1024^3 = 2^{30} (Gibi)
+          ‘T’  =>  1024^4 = 2^{40} (Tebi)
+          ‘P’  =>  1024^5 = 2^{50} (Pebi)
+          ‘E’  =>  1024^6 = 2^{60} (Exbi)
+          ‘Z’  =>  1024^7 = 2^{70} (Zebi)
+          ‘Y’  =>  1024^8 = 2^{80} (Yobi)
+
+     The ‘iec’ option uses a single letter suffix (e.g.  ‘G’), which is
+     not fully standard, as the _iec_ standard recommends a two-letter
+     symbol (e.g ‘Gi’) - but in practice, this method common.  Compare
+     with the ‘iec-i’ option.
+
+IEC-I
+     Auto-scale numbers according to the _International Electrotechnical
+     Commission (IEC)_ standard.  For input numbers, accept one of the
+     following suffixes.  For output numbers, values larger than 1024
+     will be rounded, and printed with one of the following suffixes:
+
+          ‘Ki’  =>  1024^1 = 2^{10} (Kibi)
+          ‘Mi’  =>  1024^2 = 2^{20} (Mebi)
+          ‘Gi’  =>  1024^3 = 2^{30} (Gibi)
+          ‘Ti’  =>  1024^4 = 2^{40} (Tebi)
+          ‘Pi’  =>  1024^5 = 2^{50} (Pebi)
+          ‘Ei’  =>  1024^6 = 2^{60} (Exbi)
+          ‘Zi’  =>  1024^7 = 2^{70} (Zebi)
+          ‘Yi’  =>  1024^8 = 2^{80} (Yobi)
+
+     The ‘iec-i’ option uses a two-letter suffix symbol (e.g.  ‘Gi’), as
+     the _iec_ standard recommends, but this is not always common in
+     practice.  Compare with the ‘iec’ option.
+
+AUTO
+     ‘auto’ can only be used with ‘--from’.  With this method, numbers
+     with ‘K’,‘M’,‘G’,‘T’,‘P’,‘E’,‘Z’,‘Y’ suffixes are interpreted as
+     _SI_ values, and numbers with ‘Ki’,
+     ‘Mi’,‘Gi’,‘Ti’,‘Pi’,‘Ei’,‘Zi’,‘Yi’ suffixes are interpreted as
+     _IEC_ values.
+
+26.2.3 Examples of using ‘numfmt’
+---------------------------------
+
+Converting a single number from/to _human_ representation:
+     $ numfmt --to=si 500000
+     500K
+
+     $ numfmt --to=iec 500000
+     489K
+
+     $ numfmt --to=iec-i 500000
+     489Ki
+
+     $ numfmt --from=si 1M
+     1000000
+
+     $ numfmt --from=iec 1M
+     1048576
+
+     # with '--from=auto', M=Mega, Mi=Mebi
+     $ numfmt --from=auto 1M
+     1000000
+     $ numfmt --from=auto 1Mi
+     1048576
+
+   Converting from ‘SI’ to ‘IEC’ scales (e.g.  when a harddisk capacity
+is advertised as ‘1TB’, while checking the drive’s capacity gives lower
+values):
+
+     $ numfmt --from=si --to=iec 1T
+     932G
+
+   Converting a single field from an input file / piped input (these
+contrived examples are for demonstration purposes only, as both ‘ls’ and
+‘df’ support the ‘--human-readable’ option to output sizes in
+human-readable format):
+
+     # Third field (file size) will be shown in SI representation
+     $ ls -log | numfmt --field 3 --header --to=si | head -n4
+     -rw-r--r--  1     94K Aug 23  2011 ABOUT-NLS

+     # Second field (size) will be shown in IEC representation
+     $ df --block-size=1 | numfmt --field 2 --header --to=iec | head -n4
+     File system   1B-blocks        Used  Available Use% Mounted on
+     rootfs             132G   104741408   26554036  80% /

+     /dev/sdb1          694G   651424756   46074696  94% /home
+
+   Output can be tweaked using ‘--padding’ or ‘--format’:
+
+     # Pad to 10 characters, right-aligned
+     $ du -s * | numfmt --to=si --padding=10
+           2.5K config.log
+            108 config.status
+           1.7K configure
+             20 configure.ac
+
+     # Pad to 10 characters, left-aligned
+     $ du -s * | numfmt --to=si --padding=-10
+     2.5K       config.log
+     108        config.status
+     1.7K       configure
+     20         configure.ac
+
+     # Pad to 10 characters, left-aligned, using 'format'
+     $ du -s * | numfmt --to=si --format="%10f"
+           2.5K config.log
+            108 config.status
+           1.7K configure
+             20 configure.ac
+
+     # Pad to 10 characters, left-aligned, using 'format'
+     $ du -s * | numfmt --to=si --padding="%-10f"
+     2.5K       config.log
+     108        config.status
+     1.7K       configure
+     20         configure.ac
+
+   With locales that support grouping digits, using ‘--grouping’ or
+‘--format’ enables grouping.  In ‘POSIX’ locale, grouping is silently
+ignored:
+
+     $ LC_ALL=C numfmt --from=iec --grouping 2G
+     2147483648
+
+     $ LC_ALL=en_US.utf8 numfmt --from=iec --grouping 2G
