Very roughly based on the HP-28/48 +series of calculators, its many features include: + + * Choice of algebraic or RPN (stack-based) entry of calculations. + * Arbitrary precision integers and floating-point numbers. + * Arithmetic on rational numbers, complex numbers (rectangular and + polar), error forms with standard deviations, open and closed + intervals, vectors and matrices, dates and times, infinities, + sets, quantities with units, and algebraic formulas. + * Mathematical operations such as logarithms and trigonometric + functions. + * Programmer's features (bitwise operations, non-decimal numbers). + * Financial functions such as future value and internal rate of + return. + * Number theoretical features such as prime factorization and + arithmetic modulo M for any M. + * Algebraic manipulation features, including symbolic calculus. + * Moving data to and from regular editing buffers. + * "Embedded mode" for manipulating Calc formulas and data directly + inside any editing buffer. + * Graphics using GNUPLOT, a versatile (and free) plotting program. + * Easy programming using keyboard macros, algebraic formulas, + algebraic rewrite rules, or extended Emacs Lisp. |
