# Mod Command

From GeoGebra Manual

- Mod( <Dividend Number>, <Divisor Number> )
- Yields the remainder when dividend number is divided by divisor number.
**Example:**`Mod(9, 4)`

yields*1*.

- Mod( <Dividend Polynomial>, <Divisor Polynomial> )
- Yields the remainder when the dividend polynomial is divided by the divisor polynomial.
**Example:**`Mod(x^3 + x^2 + x + 6, x^2 - 3)`

yields*4 x + 9*.

**Note:**

If you want a function to do this, you can define it yourself, e.g. `mod(x, y) = y (x / y - floor(x / y))`
