darctan2


Description

This function returns the inverse tangent of an angle y/x, where y = Opposite side of triangle and x = Adjacent side of triangle. Unlike darctan(x) the function darctan2(y, x) is valid for all angles and so may be used to convert a vector to an angle without risking division by zero, and it also returns a result in the correct quadrant.

NOTE:The value returned is in degrees, not radians.


Syntax:

darctan2(y, x);


Argument Description
y The y coordinate to calculate.
x The x coordinate to calculate.


Returns:

Real


Example:

val = darctan2(1, 1);

This will set "val" to the correct angle.
