===== Function: llAbs =====

<code lsl2>
integer llAbs(integer ival)
</code>

Return the absolute value of the parameter (for integers).

===== Parameters =====

=== ival ===
Any $lty[integer] value (can be negative)

===== Return value =====

It returns an integer that is the absolute value of $prm[ival], that is, the value with any negative sign removed.

More rigorously, the result will be the same as $prm[ival] if $prm[ival] is positive or zero, and $prm[-ival] if it is negative.

===== Notes =====

  * To determine the absolute value of a $lty[float], use $lfn[llFabs].
  * As a special case, the absolute value of -2,147,483,648 (-2<sup>31</sup>, the lowest integer LSL supports) is returned by this function as -2,147,483,648 because the positive integer 2,147,483,648 is outside the range of a LSL $lty[integer].

===== Short examples =====

<code lsl2>
integer AbsInt;
AbsInt = llAbs(-3);    // sets AbsInt to 3
AbsInt = llAbs(-45);   // sets AbsInt to 45
AbsInt = llAbs(0);     // sets AbsInt to 0
AbsInt = llAbs(45);    // sets AbsInt to 45
Absint = llAbs(AbsInt - 50); // sets AbsInt to 5 (see explanation below)
</code>
The last example assumes that ''AbsInt'' was 45 due to the previous line. 45 - 50 equals -5, and ''llAbs(-5)'' equals 5.
