Summary

Function: float llTan( float theta );
0.0 Forced Delay
10.0 Energy

Returns a float that is the tangent of theta.

• float theta angle expressed in radians

Caveats

Because of IEE754 on floats , llTan(PI_BY_TWO) returns -22877332 ( hex: 0xCBAE8A4A) and not infinity

Examples

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