Oblivion does '''not''' include a square root function. Therefore one must use this code to get the square root of a number. | |||
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.

NOTE: For a check such as the distance between two points it's not required to actually take the square root. The Forumal of Pythagoras goes A^2 + B^2 = C^2, so instead of "if sqrt(X*X + Y*Y) == C" one can use "If (X*X + Y*Y) == (C*C)", where C is the distance you want to have checked. | |||
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. | 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.
