there is no 32 bit for all ints, floats, etc...

numpy has defaults for various array constructors. Most of them default to
either double for a floating point type, or an integer that matches the
python standard integer.

On 64 bit python on *nix of OS-X, I think this means you'll get a 64 bit
integer by default, from, for example:


I don't think the default float types depend on the bit-depth of the python
you are running with.

I don't think you can change any of those defaults.
