This will only work if you are running on a system where your CPU has
a full-blown CPU,  32  bytes  cache  line  size,  and  your  run-time
environment (all system libraries) are configured to use the FPU.

It will fail on  FPU-less  or  FPU-restricted  systems  like  MPC8xx,
PPC4xx, or MPC85xx.

I guess you didn't do much testing. You should try some  mathematics,
and  you  might  be surprised what happens when your Perl binary uses
the (emulated) FPU, while the system libraries use soft-float.
