Atan2 Function

Returns the angle of the imaginary line connecting points (0,0) and (X, Y) in radians.

Syntax
Atan2(X, Y)

Parameters

X

Specify the X coordinate value as a real number value.

Y

Specify the Y coordinate value as a real number value.

Return Values
Numeric value in radians (-PI to +PI).

Description
Atan2(X, Y) returns the angle of the line which connects points (0, 0) and (X, Y).
