# jax.numpy.remainder¶

jax.numpy.remainder(x1, x2)[source]

Return element-wise remainder of division.

LAX-backend implementation of remainder(). Original docstring below.

remainder(x1, x2, /, out=None, *, where=True, casting=’same_kind’, order=’K’, dtype=None, subok=True[, signature, extobj])

Computes the remainder complementary to the floor_divide function. It is equivalent to the Python modulus operatorx1 % x2 and has the same sign as the divisor x2. The MATLAB function equivalent to np.remainder is mod.

Warning

This should not be confused with:

• Python 3.7’s math.remainder and C’s remainder, which computes the IEEE remainder, which are the complement to round(x1 / x2).

• The MATLAB rem function and or the C % operator which is the complement to int(x1 / x2).

Parameters
• x1 (array_like) – Dividend array.

• x2 (array_like) – Divisor array. If x1.shape != x2.shape, they must be broadcastable to a common shape (which becomes the shape of the output).

Returns

y – The element-wise remainder of the quotient floor_divide(x1, x2). This is a scalar if both x1 and x2 are scalars.

Return type

ndarray

floor_divide()

Equivalent of Python // operator.

divmod()

Simultaneous floor division and remainder.

fmod()

Equivalent of the MATLAB rem function.

Notes

Returns 0 when x2 is 0 and both x1 and x2 are (arrays of) integers. mod is an alias of remainder.

Examples

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