Re: why do ceil/floor give the decimal dot?

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?
