=roundup() takes two arguments.

If you mean:
=ROUNDUP(INT(0.9999),0)

then 0 looks like the only correct answer to me.

=int(0.9999) will be 0
=roundup(0,0) will still be 0.

This function should always return 0, correct?

Ex.: =ROUNDUP(INT(0.9999)) is really =ROUNDUP(0)

A colleague claims this is a bug in Excel; I claim this is correct.
