{{函数详情
|函数名 = Function: integer llRound( float val );
|参数= 参数：• float val  - 任何有效的浮点值
|返回值= 返回值：返回val最接近的整数。

如果十分位的绝对值小于或等于4，则val四舍五入;否则，val将四舍五入到正无穷。

|注意事项=如果算术结果超出了有效整数的范围(-2147483648到2147483647包括在内)，则返回值为-2147483648 (0x80000000)。

   {  
       llSay(0,  "The rounded value of -4.9 is: "+(string)llRound(-4.9) );
       //Returns "The rounded value of -4.9 is: -5"
 
       llSay(0,  "The rounded value of -4.1 is: "+(string)llRound(-4.1) );
       //Returns "The rounded value of -4.1 is: -4"
 
       llSay(0,  "The rounded value of 4.5 is: "+(string)llRound(4.5) );
       //Returns "The rounded value of 4.5 is: 5"
 
       llSay(0,  "The rounded value of 4.9 is: "+(string)llRound(4.9) );
       //Returns "The rounded value of 4.9 is: 5"
 
       llSay(0,  "The rounded value of 4.1 is: "+(string)llRound(4.1) );
       //Returns "The rounded value of 4.1 is: 4"
 
       llSay(0,  "The rounded value of -4.5 is: "+(string)llRound(-4.5) );
       //Returns "The rounded value of -4.5 is: -4"
