Hey Numpy people!
I just compiled the last NumPy. Underflows don't give zero but generate
OverflowError:
Python 2.0 (#2, Dec 15 2000, 15:04:31)
[GCC 2.95.2 19991024 (release)] on linux2

Hello from .pythonrc.py
>>> import Numeric
>>> Numeric.__version__
'17.2.0'
>>> Numeric.exp(-1.42676746e+12)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
OverflowError: math range error
>>>
How to suppress these? Any hint?
