/* On Intel Pentium processors (especially PIII and probably P4), converting
** from float to int is very slow. To meet the C specs, the code produced by 
** most C compilers targeting Pentium needs to change the FPU rounding mode 
** before the float to int conversion is performed. 
**
** Changing the FPU rounding mode causes the FPU pipeline to be flushed. It 
** is this flushing of the pipeline which is so slow.
