ATAN2


Returns the arctangent of a ratio

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).

Examples:
Print Atan2 ( 4, 5 )     'this is the same as PRINT ATN ( 4 / 5 )


The output would be:
0.6747409422235527
