IsOdd: Bug?

[Torsten Anders]

Dear all,

the function IsOdd currently always returns false for negative  
numbers. Is there some reason for this? Otherwise I would change the  
current implementation

   fun {IsOdd X}  X mod 2 == 1 end

into

  fun {IsOdd X}  {Abs X mod 2} == 1 end

Thanks!

Best
Torsten

PS: thanks to Wolfgang for his code navigator: finding the source of  
IsOdd only took a single key stroke :)
