Re: [Numpy-discussion] Handling underflow

Is there some way of having calculations which cause underflow automatically set their result to 0.0? For example when I take exp(a), where a is a floating point array.

Not 'automatically', but: a = whatever() choose(greater(a, MAX), (a, MAX)) answer = exp(-a) any good? This is with a 1D array -- I haven't used higher dimensions much. John
