Hi, I'm using Konrad Hinsen's LeastSquares.leastSquaresFit for a convenient way to do a non linear minimization. It uses the "old" Numeric module. But since I upgraded to Numeric 24.2 I get OverflowErrors that I tracked down to
Numeric.exp(-760.) Traceback (most recent call last): File "", line 1, in ? OverflowError: math range error
From numarray I'm used to getting this:
na.exp(-760) 0.0
Mostly I'm confused because my code worked before I upgraded to version 24.2.
Thanks for any hints on how I could revive my code... -Sebastian Haase
