{{函数详情<br />
|函数名 = Function: float llCos( float theta );<br />
|参数= 参数： float theta – angle expressed in radians(以弧度表示的浮动θ角) <br />
|返回值= 返回值：返回一个浮点数，它是θ的余弦<br />
<br />
|注意事项=因为 iee754在 single floats 上，llcos (pi by two)返回-4.371139 e-8(hex: 0x33bbd2e)而不是0; llcos (pi / 3.0)返回0.49999997(hex: 0x3effff)而不是0<br />
