This uses Newton-Raphson approximation, and gives accuracy to two decimal places for numbers less than or equal to 100. Adding more steps to it increases accuracy very quickly. | This uses Newton-Raphson approximation, and gives accuracy to two decimal places for numbers less than or equal to 100.

This is a [ | This is a [:Category:Stage_Functions|Stage Function], and as such must be created as a [[Quest Stages Tab|Quest Stage]] of a global script and called as a function. This assumes a [[Quest]] called Wiki with the variables declared. Therefore, you must modify this code to include the name of your [[Quest]] (assuming it is not Wiki, which it shouldn't be). Alternatively, however, it would not be difficult to incorporate this code into your script directly. | ||

You are free to rename either, but remember to change the function code. | Your input variable need not necessarily be a float, it could be a short or long, but SqRt needs to be a float, as few square roots are integers. You are free to rename either, but remember to change the function code. | ||
