You mean like this?
$ printf "%d\n" $(( 7.5 + 0.5 ))

No, I don't care what data type is used as long as
1. ceil and floor return integers in the math
sense (otherwise the function I just posted is
is incorrect); and
2. when the result is printed, it is printed as
x (and not "x.") for an integer x, because
otherwise I can't use that function in scripts
and functions without removing the dot
each time.
Or, do you think the "unbroken chain of floats"/"the
shell will deal with it"-approach instead should be
put to use, i.e. rolling with the punches, e.g.
$ g () { return 6.0 }; g; b=$?; printf "%d\n" $b

Is that what you are saying?
