Summary

Function: float llAtan2( float y, float x );
0.0 Forced Delay
10.0 Energy

Returns a float that is the "Wikipedia logo"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.

Examples

<lsl>default {

 state_entry()
 {
   float num1 = llFrand(100.0);
   float num2 = llFrand(100.0);
   llOwnerSay("y = " + (string)num1);
   llOwnerSay("x = " + (string)num2);
   llOwnerSay("The tangent of y divided by x is " + (string)llAtan2(num1, num2));
 }
}</lsl>
