numpy.remainder(x1, x2[, out]) = <ufunc 'remainder'>

Return element-wise remainder of division.

Computes x1 - floor(x1 / x2) * x2, the result has the same sign as the divisor x2. It is equivalent to the Python modulus operator x1 % x2 and should not be confused with the Matlab(TM) rem function.

Parameters :

x1 : array_like

Dividend array.

x2 : array_like

Divisor array.

out : ndarray, optional

Array into which the output is placed. Its type is preserved and it must be of the right shape to hold the output. See doc.ufuncs.

Returns :

y : ndarray

The remainder of the quotient x1/x2, element-wise. Returns a scalar if both x1 and x2 are scalars.

See also

Equivalent of the Matlab(TM) rem function.

divide, floor


Returns 0 when x2 is 0 and both x1 and x2 are (arrays of) integers.


>>> np.remainder([4, 7], [2, 3])
array([0, 1])
>>> np.remainder(np.arange(7), 5)
array([0, 1, 2, 3, 4, 0, 1])
