Replace -inf with zero value

Question

I have an array:

x =  numpy.array([-inf, -inf, 37.49668579])

Is there a way to change the -inf values to just 0?

Answer 1

There is:

from numpy import inf
x[x == -inf] = 0

Answer 2

Use isneginf http://docs.scipy.org/doc/numpy/reference/generated/numpy.isneginf.html#numpy.isneginf

x[numpy.isneginf(x)] = 0
