absolutely, and I think there was a wide range of opinions about how usefull (and or critical!) this is.

numarray allows one to customize how errors are handled. You can choose:

1. to silently ignore all errors.
2. print a warning message (default)
3. raise an exception.

One may separately set one of these three behaviors for each of the 4 ieee categories of floating point errors, namely

1. invalid results (i.e., NaNs)
2. divide by zeros (Infs)
3. overflows
4. underflows

Fabulous!!! You folks are wonderfull! I guess it's time to make the switch to numarray...I've been waiting for a compelling reason!
