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.

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)); }
}
