How do I use square root in AS2?

[UberCream]

Someone please help me. I am making a game that uses distance formula and to calculate distance, you need square root. Does anyone know how to make a square root symbol (probably using some kind of alt-code) that would work in as2. Also, I need to know how to apply it. For example, would i say (if i want to find the square root of variable a + variable b) would it be [sq. rt. symbol] * (a+b) or would i have to do something else?

If you want the square root of a + b simply use this:

Math.sqrt(a+b)

Wow, thanks! I tested it out and it worked!

Here is the test! You can drag around the red circle!

Why did you have to use square root to do that?

x cord 2 - x cord 1

ycord 2 - y cord 1

xdiff + ydiff sqrted is distance. simple pythagus theorum.

Oh, for the distance. I thought he was trying to use sqrt to move the dot around.

Nein, xdiff^2 + ydiff^2 sqrted is distance.
