CEILING function substitute for 35s

[Martin Pinckney]

Does anyone know a set of functions that combined, will return the same result as the CEILING function (38G)?

Will be used on the 35s.

Thanks for any ideas.

For the FLOOR function: left shift-INTG-4


For the CEIL function: do the above and add 1

Not really so! CEIL(x) is *equal* to FLOOR(x) if x is an integer!

I don't have a 35s yet but CEIL(x) = -FLOOR(-x), so a solution is to write a short program executing

NEG FLOOR NEG

Which would be wrong when the argument is an exact integer.

Of course, the more enlightened posters above me are right!

But with that neat NEG FLOOR NEG trick everything is provided for...;-)
