The following seems to show that the default data type for the numarray
elements is Int32:
Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32 bit (Intel)]
Type "help", "copyright", "credits" or "license" for more information.
>>> import numarray as _n
>>> a= _n.zeros(shape=(3, 3))
I don't use the typecodes as the numerictypes are much more explicit.
