# scipp.mod¶

scipp.mod(dividend, divisor)

Element-wise remainder.

This function corresponds to the modulus operator `dividend % divisor`.

In scipp, the remainder is defined to complement `scipp.floor_divide()` meaning that

```a == floor(a / b) * b + a % b
```

This is the same definition as in `numpy.mod` and `numpy.remainder`.

Warning

This differs from the IEEE 754 remainder as implemented by `math.remainder()` and C’s remainder function and modulus operator, which complement `round(a / b)`.

Parameters
• dividend (VariableLike) – Dividend of the quotient.

• divisor (VariableLike) – Divisor of the quotient.

Returns

Quotient.

Return type

VariableLike

Examples:

```>>> sc.mod(sc.arange('x', -3, 5), sc.scalar(3)).values
array([0, 1, 2, 0, 1, 2, 0, 1])
>>> sc.mod(sc.arange('x', -3, 5), sc.scalar(-3)).values
array([ 0, -2, -1,  0, -2, -1,  0, -2])
```

Of equivalently in operator notation

```>>> (sc.arange('x', -3, 5) % sc.scalar(3)).values
array([0, 1, 2, 0, 1, 2, 0, 1])
```
