| • integer | b | |||
| • integer | c |
Examples
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.[1]
