Summary
Function: float llSin( float theta );0 | Function ID |
0.0 | Forced Delay |
10.0 | Energy |
Returns a float that is the sine of theta.
• float | theta | – | angle expressed in radians |
Caveats
Because of IEE754 on floats , llSin(PI) returns -8.742278E-8 ( hex : 0xB3BBBD2E ) and not 0.0 . The error is cumulative with multiples of PI : For instance llSin(100000.0*PI) = 0.015890 when the result should be 0.0
Examples
// Touch the object with this script in it to see the sine of random numbers!
default
{
touch_start(integer num)
{
float r = llFrand(TWO_PI);
llOwnerSay("The sine of " + (string)r + " in radians or " + (string)(r * RAD_TO_DEG) + " in degrees is " + (string)llSin(r));
}
