cumprod(self, axis=None, dtype=None, out=None)¶
Return the cumulative product of the array elements over the given axis.
Masked values are set to 1 internally during the computation. However, their position is saved, and the result will be masked at the same locations.

The mask is lost if out is not a valid MaskedArray !
Arithmetic is modular when using integer types, and no error is raised on overflow.
