	I am using a Genuine Pentium 150 (Classic).  And floating point operations
take much longer than integer.  I think it is about 5 times slower for
floating point stuff.  A floating point multiply takes about the same time as
a floating point add, so if fadd's were as fast as add's then fmul's would be
significantly faster than mul's.  And everyone would use fmul's!!
