FP is an Xcode C++ project which implements unlimited length integers, multi-precision floating point numbers, fractions with unlimited length integers as num/den, and multi-precision complex numbers. It can calculate the usual transcendental functions, including the Gamma function and other special functions. I am releasing it without a restrictive license.
