llCos

Summary

Function: float llCos( float theta );

0.0	Forced Delay
10.0	Energy

Returns a float that is the cosine of theta.

• float

theta

–

angle expressed in radians

Caveats

because of IEE754 on single floats, llCos(PI_BY_TWO) returns -4.371139E-8 (hex : 0xB33BBD2E ) and not 0 ; llCos(PI/3.0) returns 0.49999997 ( hex : 0x3EFFFFFF ) and not 0.5

Examples

// Touch the object with this script in it to see the cosine of random numbers!
default
{
    touch_start(integer num)
    {
        float r = llFrand(TWO_PI);
        llOwnerSay("The cosine of " + (string)r + " in radians or " + (string)(r * RAD_TO_DEG) + " in degrees is " + (string)llCos(r));
    }
}
