Your benchmark looks ok, thanks, although the difference is a little smaller on my machine (-21% / +27%). I did surround your three divisions with int() in the no_integer version.

The above results show that my machine has not floating point hardware?

I doubt it, rather I guess that Perl can simply use more efficient implementations of the mathematical opcodes, that don't need to worry about all the floating-point stuff that Perl hides in its numerical types.
