llAbs

Function: integer llAbs( integer val );

Returns an integer that is the positive version of val.

• integer val – Any integer value  

This function is similar to functions (<e.g. abs) found in many other languages such as C++

Caveats

• The llAbs of -2147483648 is -2147483648. This is because the positive integer 2147483648 is outside the range of allowed LSL integer values.

Examples

Example 1

default {

   state_entry()
   {

// returns: "The absolute value of -4 is: 4"

       llSay(PUBLIC_CHANNEL, "The absolute value of -4 is: "+(string)llAbs(-4) );
   }

} 

Example 2

// 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
   }

} 

Notes

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