Eh, what? numpy.float is Python's float. No numpy features at all.
There is some preprocessing, specifically to handle edge conditions
like .1, and Python 2.6 handles 'nan', but the important point is that
we don't control that code. You will have to submit a bug report to
Python in order to change that behavior.

That said, numpy.float64() is under our control, and you may submit a
patch to convert [dD] to [eE].
