Summary

Function: float llCos( float theta );

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
