> Do anyone know how to disable underflow exception errors in Numeric?

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.
