ATan2 (arctangent)
ATan2 Function
Calculates the arctangent, or inverse tangent, of the specified x- and y-coordinates. The arctangent is the angle from the x-axis to a line containing the origin (0, 0) and a point with coordinates (x_num, y_num). The angle is given in radians between -pi and pi, excluding -pi.
Syntax
ATan2(scalar X, scalar Y)
Arguments
| Argument | Description |
|---|---|
scalar X | X-coordinate for which the arctangent is to be calculated |
scalar Y | Y-coordinate for which the arctangent is to be calculated |
Examples:
ATan2(0,5)
Returns the value in radians of Arc tangent of specified X- coordinate and Y- coordinate.
