float llSqrt(float fval)

Return the square root of the argument, that is, the number that multiplied by itself gives the argument.

The float value to take the square root of.

The square root of the given float.

• If you need the square root of 2, using SQRT2 instead of calling this function will save code and processing time.
• Any value less than zero will return NaN under Mono and crash with a math error under LSO.

float f;
f = llSqrt(4); // sets f to 2.0 because 2*2=4
f = llSqrt(25); // sets f to 5.0 because 5*5=25
f = llSqrt(-1); // sets f to NaN (Not a Number) under Mono; crashes under LSO

• llPow raises a number to any power.
• SQRT2 is a constant with the square root of 2.
