Atan2
Returns the arctangent of a ratio
result = ATan2( y, x )
y
The angle whose tangent is y/x, in radians, in the range [-Pi..Pi].
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).
The output would be:
Syntax
Usage
result = ATan2( y, x )
Parameters
y
Vertical component of the ratio.
xHorizontal 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).
Example
Print Atan2 ( 4, 5 ) 'this is the same as PRINT ATN ( 4 / 5 )
The output would be:
0.6747409422235527
