Chris (and everyone else):
I've just added an nbytes dictionary to scipy core.
You can now say
scipy.nbytes[<any recognized type alias>]
and get the number of bytes
thus
scipy.nbytes['d']
scipy.nbytes[scipy.float_]
scipy.nbytes[float]
scipy.nbytes[scipy.float64]
scipy.nbytes[scipy.Float64]
all return the same thing: 64
There is also a new nbytes attribute of ndarray's that does the itemsize
* size multiplication for you to give the number of bytes in the array.
