Subject: Integer or Floating Point for Scoring?

Author: Larry Griffiths

I have been using Floating point (double) for my evaluation (scoring)
function.  I set some variables to 0.0 when starting the Alpha-Beta search.
I add values to these variables when a move is made and then subtract them
back out when restoreing the piece.  I have found that the result is not
always returned back to 0.0.  I get something like 3.56234567343534-18.

Should I be using integers for scoring instead?

Thanks in advance!   :->
