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).
Example
Print Atan2 ( 4, 5 ) 'this is the same as PRINT ATN ( 4 / 5 )
The output would be:
0.6747409422235527
