Summary
Function: float llTan( float theta );| 2 | Function ID |
| 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));
}
