Apfp (Arbitrary Precision Floating Point) is a Ruby class for performing arbitrary precision floating point calculations. It also includes a class Apc for calculating with arbitrary precision complex numbers. It also contains a Real class for built-in reals. Both classes keep an estimate of the accumulated error.

Release Notes: The logarithm functions were greatly improved. norm and sqrt were also improved.
Release Notes: Small changes in support of rubysode.
