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));
  }
}

Notes

If you need the square root of two use SQRT2.
