LlAtan2

From OSgrid Wiki

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

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.

Examples

<source lang="lsl">

default {

 state_entry()
 {
   float num1 = llFrand(100.0);
   float num2 = llFrand(100.0);

   llOwnerSay("y = " + (string)num1);
   llOwnerSay("x = " + (string)num2);

   llOwnerSay("The arctangent of y divided by x is " + (string)llAtan2(num1, num2));
 }
