Hey Numpy people! Do anyone know how to disable underflow exception errors in Numeric? I have a lot of these in my code. It is now a very important problem in my calculations. The only solution I see is to make a for loop and make the arithmetic in python instead of Numeric. Thanks for your help, Jean-Bernard Python 2.0 (#9, Feb 2 2001, 12:17:02) [GCC 2.95.2 19991024 (release)] on linux2 Type "copyright", "credits" or "license" for more information. Hello from .pythonrc.py
import Numeric Numeric.__version__ '17.2.0' Numeric.array([2.9e-131])**3 Traceback (most recent call last): File "<stdin>", line 1, in ? OverflowError: math range error 2.9e-131**3 0.0

The problem is not in Numeric, it is the C library that decides whether underflows should be considered errors or not. The Python interpreter has some workarounds, but Numeric has not. I had the same problems you describe under AIX, where I solved them by linking to a different version of the math library. But I don't think there is a platform-independent solution.
