I tried this on my installation (Win2K3 64 bit, Apache, PHP 5.2.3) the
calculation worked as expected. I also took the time to upgrade to
5.2.5 (which was harder than it should of been, I had to repair the
installation before Apache could run with the dlls). Having got it
running, the calculation once again produced the expected result..
Incidentally, your use of var_dump is incorrect. It doesn't return a
value, but sends output directly
