Calc

http://www.isthe.com/chongo/tech/comp/calc/
C-style arbitrary precision arithmetic system

Calc is an arbitrary precision arithmetic system that uses a C-like language. It's useful as a calculator, an algorithm prototype, and as a mathematical research tool. More importantly, calc provides a machine-independent means of computation. Its features include:

  • Arbitrary precision integers and floating-point, fractions and complex values
  • Logarithm, numeric, trig, hyperbolic functions
  • C-like syntax
  • calc shell scripts, resource files, linkable program library
  • User defined finctions and function loading
  • Over 283 built-in functions plus hooks for built-in custom extensions
  • Arrays, lists, dynamic strings, matrices, associate arrays, objects
  • Numeric, relational, boolean and variable access operators
  • Extensive string and binary block memory builtin functions
  • Matrix inversion, determinant, and other matrix operations
  • Fast and cryptographic pseudo-random numbers, cryptographic hashes
  • Factoring, primality tests, pi(x), multiplicative inverse, modular exp
  • Bernoulli numbers, Euler numbers, Catalan numbers
  • Uses REDC, splint-point and other high speed multi-precision algorithms
  • Extensive regression test suite
  • Resource functions: large prime tests, factoring, quaternions, etc.
  • File I/O, multi-precision printf and scanf, stdio-like functions
  • GNU Readline, user & system startup scripts, Emacs-style line editing
  • Online help
