C alc is an arbitrary precision arithmetic system that uses a C-like language.
Calc is useful as a calculator, an algorithm prototyper and as a mathematical research tool. More importantly, calc provides one with a machine independent means of computation. Calc comes with a rich set of builtin mathematical and programmatic functions. Calc is built on top of the library libcalc that represents numeric values as fractions reduced to their lowest terms. Martin Buck is responsible for this Debian package.
