float llSqrt(float fval)

Return the square root of the argument, that is, a number such that when multiplied by itself, results in the given 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
instead of calling this function will save code and processing time.**SQRT2** - An input of -0.0 will return -0.0.
- Any value less than zero will return
**NaN**.

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(2); // sets f to approx. 1.414214, which multiplied by itself gives approx. 2 f = SQRT2; // same as above, but more efficient f = llSqrt(-1); // sets f to NaN (Not a Number) under Mono; crashes under LSO
