Syntax:
Usage:
result = ATan2( y, x )
Parameters:
y
Vertical component of the ratio.
x
Horizontal component of the ratio.
Return Value:
The angle whose tangent is y/x, in radians, in the range [-Pi..Pi].
Description:
ATan2 returns the arctangent of the ratio y/x as a Double within the range of -Pi to Pi. The arctangent is the inverse of the Tan function. The returned angle is measured in radians (not degrees).
ATan2 cannot be overloaded as operator to accept user-defined types.
