hfloat

hfloat (for 'huge float') is a library package (coming as C++ code) for calculations with floating point numbers of extreme precision. It is optimised for computations with 1000...several million digits. hfloat utilises FFT multiplication technique. Included is the fxt-library, containing many FFT-implementations, code for convolution, correlation etc. Several algorithms for the computation of pi are implemented. The computations can be done in (almost) arbitrary radix. Documentation is in here
