I wonder if math is use in scripting.

Because i saw on LuxAdmin while i'm reviewing it.
It seems like this.

pawn Код:

RX = startX - endX;
    RY = startY - endY;
    RZ = startZ - endZ;
    new Float:sqrt = floatsqroot((RX * RX) + (RY * RY) + (RZ * RZ));
    if (sqrt < 0.01)
        sqrt = 0.01;
    RX = -length * (RX / sqrt) + startX;
    RY = -length * (RY / sqrt) + startY;
    RZ = -length * (RZ / sqrt) + startZ;

on the stock function GetOnLine3D.

What it does means?.

Is Math really use in scripting some how?
