If you accessed the variable like $this, then it's more or less the
same issue.

It's just part of how the shell represents floating point numbers;
it has nothing to do with FORCE_FLOAT specifically.

	% unsetopt FORCE_FLOAT
	% echo $((1.0))
	1.

I don't know if there's a reason for not including a trailing "0".

That would lose information, so instead of this:

	% x=$((1.0))
	% typeset -p x
	typeset x=1.
	% print $((x / 2))
	0.5

you would get this:

	% x=$((1.0))
	% typeset -p x
	typeset x=1
	% print $((x / 2))
	0
