Summary

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

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));
  }
}
