Description
Returns the arc tangent of v1/v2 (in radians), but uses the signs of both parameters to find the quadrant of the result. (It also handles correctly the case of v2 being zero.)
(number) = math.atan2(v1,v2)
Parameters
v1: (number) first value
v2: (number) second value
Return values
Returns (number) result
