python - How to handle ZeroDivisionError inside numpy array -


i have 2 big numpy arrays, need divide them.

since working on python 32-bits, , arrays big, avoid floatingpointerror, doing, example:

x = numpy.array([...],dtype=object) y = numpy.array([...].dtype=object)

the problem that, inside array y, elements can 0.0

so, question, how handle calculation x/y , avoid zerodivisionerror.

for exmaple, force nan if element in y 0. that, particular element inside array, calculation x/y=nan

use masked arrays,

x = numpy.array([...],dtype=object) y = numpy.array([...].dtype=object)  x_m = numpy.ma.array(x, mask=~(x==0)) y_m = numpy.ma.array(y, mask=~(y==0))  print(x_m/y_m)
