Summary
Function: float llSqrt( float val );| 0.0 | Forced Delay |
| 10.0 | Energy |
Returns a float that is the square root of val.
| • float | val | – | positive number (val >= 0.0) |
For imaginary results (val < 0.0), a Math Error is triggered under LSO , or 'NaN' (Not A Number) is returned under Mono
Caveats
- Crashes the script if passed a negative number.
Examples
default
{
state_entry()
{
float num1 = llFrand(100.0);
llOwnerSay("The square root of " + (string)num1 + " is " + (string)llSqrt(num1));
}
}
