# llModPow

*LSL function*

```lsl
integer integer llModPow(integer base, integer exponent, integer modulus);
```

- `integer base`: 32-bit unsigned integer base.
- `integer exponent`: 32-bit unsigned integer exponent.
- `integer modulus`: 32-bit unsigned integer modulus.

- Returns: `integer`
- Energy: 10

Returns base raised to the power exponent, modulo modulus (i.e., (b^e)%m). All inputs are wrapped to unsigned 32-bit integer range [0..4294967295]. Output is wrapped to signed 32-bit integer range [-2147483648..2147483647]. Will never overflow, unlike (b^e), which can overflow to inf.

Returns an [integer](https://wiki.secondlife.com/wiki/integer) that is **a** raised to the **b** power, mod **c**. ( (**a**\*\***b**)%**c** )

```lsl title="How to use" frame="terminal"
integer result = llModPow(0, 0, 0);
```

## Examples

<summary>Example 1</summary>

```lsl
integer x = llModPow(13743, 14200, 10000); // = 1
integer y = llModPow(0xc734abfa, 0x8371b314, 0xffffffff); // = -1481328730, corresponding to unsigned value of 2813638566
```

## Notes

- Internally, the parameters are considered unsigned integers. This means it's possible to get extra range by using negative values or hexadecimal, and interpreting the result as such as well.
- This function used to have a forced delay of 1.0 and precision issues before an update in January 2025.[^wiki-4fe61f]
