| Parameters : | x1 : array_like 
 x2 : array_like 
 out : ndarray, optional 
  | 
|---|---|
| Returns : | y : ndarray

Notes
Returns 0 when x2 is 0 and both x1 and x2 are (arrays of) integers.
Examples
>>> np.remainder([4, 7], [2, 3])
array([0, 1])
>>> np.remainder(np.arange(7), 5)
array([0, 1, 2, 3, 4, 0, 1])
