Hey Numpy people!
This a PS from my previous message. I just tried the underflow with complex :
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
Numeric.array([2.9e-131+0j])**3
array([ 0.+0.j])
Now I have a quick solution for my problem, but I have the impression that this is a bug, at least I don't understand the underlying logic. If somebody can explain it to me?

The power calculation routines for float and complex are completely different, I suppose the absence of underflow reporting in the latter is just a side effect.
