This block is part of the [`math`](https://docs.rual.nl/block-types/math) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

Returns the remainder left over when one operand is divided by a second operand.

- number_0 required `number`

- number_1 required `number`

- Number `number`

| `mod` |
| --- |
| `remainder` |
| `modulo` |

A typical wiring for [%](https://docs.rual.nl/block-types/math/number_modulus): the `number` out pin feeds [cast to value](https://docs.rual.nl/block-types/type%20casting/number_convert_to_value).
