hfloat (for huge floats) is a library package for
doing calculations with floating point numbers of
extreme precision. It is optimised for
computations with 1000 to several million digits.
The computations can be done in (almost) arbitrary
radix. The library contains routines for addition,
subtraction, multiplication, division, n-th power,
square root, n-th root, logarithm, exponentiation
and more. There are implementations of several
superlinear converging algorithms for the
computation of pi. The computation of 1 million
decimal digits of pi takes about 15 seconds on an
AMD64/2.2GHz.
