Summary

Function: float llAtan2( float y, float x );

3	Function ID
0.0	Forced Delay
10.0	Energy

Returns a float that is the arctangent2 of y, x.

• float	y
• float	x

Similar to the arctangent(y/x) except it utilizes the signs of x & y to determine the quadrant. Returns zero if x and y are zero.
