[Numpy-discussion] How to tell whether I am using 32 bit or 64bit numpy?

Uhmmm!  I installed 64-bit Python (2.5x) on a Windows 64-bit Vista machine (yes, strange but true) hoping that the 32-bit Numpy & Scipy libraries would work but they didn't.

  In [3]: from platform import machine

  In [4]: print machine()

  Now I'm wondering why the OS isn't 64 bit but that's not for discussion
  here I guess.

What really matters is if python is 64 bits. Most 64 bit systems also run 32 bit binaries.
