[Numpy-discussion] numpy.where behavior

[<val...@bl...>]

Using numpy 1.0, why does



>>> a = numpy.array([0.0,1.0,2.0],'d')

>>> numpy.where(a
== 0.0,1,1/a)



give the correct result, but with the warning "Warning: divide
by zero encountered in divide"?



? I thought that the point of where was
that the second expression is never used for the elements where the condition
evaluates true. 



If this is the desired behavior, is there a way to suppress
the warning?



Thanks!
