You are slightly right, but not at all.

Draw score is 0.00 (Unless you tweak it), that means the Engine knows it's going
to draw (Though most of the time the 0.00 goes away after a while). A score
higher or lower than 0.00 means someone has an advantage... Even an advantage of
0.10 (1/10 of a pawn) doesn't mean draw.

I think the main poster wanted to know if any engine give the CORRECT score of
0.00 and not something lower (Black has advantage) or higher (White has
advantage).

If 0.50 meant neither side has advantage, then an engine could pick any move at
random as long as it doesn't goes below/avobe the 0.50 margin to give the enemy
advantage. They wouln't since they'd lose, just try it in CB's friendly mode in
where choosing 0.50 has this effect, 1.00 is just slightly better than 0.99,
0.99 doesn't mean "neither side has an advantage" just as 0.50, 0.49, or 0.51
doesn't mean either.

Best Regards.
