I wrote a script that calculates the square root of a number below 100 with in 0.4 acuralty.
The problem is if I type in a letter instead of a number the script locks up, and spits out "math error"..how can I wright in some code to make sure the values entered are numbers, and not letters befor they are processed?

I take it you mean its accurate to 0.4% accurate. Is that more accurate then llSqrt? I doubt you will get anything more accurate then llSqrt, you will have problems with floating point rounding errors otherwise. Just check to see if the input is zero, if it's zero return zero. //
float Sqrt(string str_input)
{
float in = (float)str_input;
if(in > 0.0)
return llSqrt(in);
return 0.0;
}
//

I was testing a method of finding square roots the long way by running it threw a loop repeadly. It was off by +-.4 of the cheating way llSqrt();
Your method works well for error handeling =-)
