Summary

Function: float llAsin( float val );
0.0 Forced Delay
10.0 Energy

Returns a float that is the arcsine in radians of val

• float val must fall in the range [-1.0, 1.0]

The returned value is in the range [-PI_BY_TWO, PI_BY_TWO][1], or NaN signifying a complex result when the parameter is out of range.

Caveats

  • Triggers a Math Error for complex results if not compiled in Mono.

Examples

<source lang="lsl2">// Touch the object with this script in it to see the arcsine of random numbers! default {

   touch_start(integer num)
   {
       float r = llFrand(2) - 1.0;
       llOwnerSay("The arcsine of " + (string)r + " is " + (string)llAsin(r));
   }
