llAbs

integer llAbs(integer Value)

Returns the absolute (positive) version of Value.

Parameters
Value (integer)
An integer value.
Technical Details
  • Return Type: integer
  • Energy: 10
default
{
    state_entry()
    {
//      returns: "The absolute value of -4 is: 4"
        llSay(PUBLIC_CHANNEL, "The absolute value of -4 is: "+(string)llAbs(-4) );
    }
}

Here’s a more elaborate example:

ShowAbsolute(integer inputInteger)
{
    string output = "llAbs(" + (string)inputInteger + ") --> " + (string)llAbs(inputInteger);


    llSay(PUBLIC_CHANNEL, output);
}


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

Caveats

Section titled “Caveats”
  • The llAbs of -2147483648 is -2147483648. This is because the positive integer 2147483648 is outside the range of allowed LSL integer values.

Notes

Section titled “Notes”
  • Using val-(val<<1)*(val<0) is roughly two times faster than llAbs, as it avoids a function call and produces identical results.
