Library for arbitrary precision arithmetic
This package contains the library libcalc.a and the necessary header files which provide routines to handle arbitrary precision arithmetic with integers, rational numbers, or complex numbers. There are also many numeric functions such as factorial and gcd, along with some transcendental functions such as sin and exp. . This library is also used by the commandline calculator `calc', which is provided in the Debian package `apcalc'.
