{{函数详情
|函数名 = Function: float llCos( float theta );
|参数= 参数： float theta – angle expressed in radians(以弧度表示的浮动θ角)	
|返回值= 返回值：返回一个浮点数，它是θ的余弦

|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

|示例=
<pre>
// Touch the object with this script in it to see the cosine of random numbers!
default
{
    touch_start(integer num)
    {
        float r = llFrand(TWO_PI);
        llOwnerSay("The cosine of " + (string)r + " in radians or " + (string)(r * RAD_TO_DEG) + " in degrees is " + (string)llCos(r));
    }
}
<pre>
