[Numpy-discussion] old-Numeric: OverflowError on exp(-760)

[Sebastian H. <ha...@ms...>]

Hi,
I'm using Konrad Hinsen's LeastSquares.leastSquaresFit for a convenient way=
 to=20
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 do=
wn=20
to=20
>>> Numeric.exp(-760.)
Traceback (most recent call last):
  File "<input>", line 1, in ?
OverflowError: math range error

=46rom 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...
