{{函数详情
|函数名=Function:integer llCeil(float val);
|参数=参数：Float val-任何有效的 float 值
|返回值=返回值:返回一个整数，该整数值是向正无穷大舍入的 val 值(返回 val)


|注意事项=如果算术结果超出有效整数的范围(- 2147483648至2147483647) ，则返回值为-2147483648(ox80000000)

<pre>

       llSay(0, "The ceil value of -4.5 is: " + (string)llCeil(-4.5));
//              "The ceil value of -4.5 is: -4"
 
       llSay(0, "The ceil value of -4.9 is: " + (string)llCeil(-4.9));
//              "The ceil value of -4.9 is: -4"
 
       llSay(0, "The ceil value of -4.1 is: " + (string)llCeil(-4.1));
//              "The ceil value of -4.1 is: -4"
 
       llSay(0, "The ceil value of 4.5 is: " + (string)llCeil(4.5));
//              "The ceil value of 4.5 is: 5"
 
       llSay(0, "The ceil value of 4.9 is: " + (string)llCeil(4.9));
//              "The ceil value of 4.9 is: 5"
 
       llSay(0, "The ceil value of 4.1 is: " + (string)llCeil(4.1));
//              "The ceil value of 4.1 is: 5"
