Summary

Function: float llSin( float theta );

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
