Written by Carsten Sonne Larsen <cs@innolan.net>. Floating point to
string conversion is based on software written by Ryan Juckett. The
code in complex calculations is derived from software written by
Stephen L. Moshier. The code in MemSet and MemCopy is derived from
software contributed to Berkeley by Mike Hibler and Chris Torek.
