| Function: integer llAbs( integer val ); |
| 参数：integer val – Any integer value |
| 返回值：Returns an integer that is the positive version of val. |
| 注意事项 |
|---|
| The llAbs of -2147483648 is -2147483648. This is because the positive integer 2147483648 is outside the range of allowed LSL integer values. |

示例1
default
{
state_entry()
{
// returns: "The absolute value of -4 is: 4"
llSay(PUBLIC_CHANNEL, "The absolute value of -4 is: "+(string)llAbs(-4) );
}
}
示例2
// Here's a more elaborate example.
ShowAbsolute(integer inputInteger)
{
string output = "llAbs(" + (string)inputInteger + ") --> " + (string)llAbs(inputInteger);
llSay(PUBLIC_CHANNEL, output);
}
default
{

{
ShowAbsolute(-3); // llAbs(-3) --> 3
ShowAbsolute(5); // llAbs(5) --> 5
ShowAbsolute(-20); // llAbs(-20) --> 20
ShowAbsolute(0); // llAbs(0) --> 0
