Fast FEXP approximation

by Ian Osgood <iano@[EMAIL PROTECTED] > Mar 25, 2008 at 07:45 AM

I recently ran across a fast approximation for exp() which relies on
the internal structure of IEEE doubles, implemented as a cast integer
multiply by a magic constant. Is this already known to the Forth
community?
