In Perl 5, ceil is in package POSIX and it is (together with floor) the recommended way to do a unilateral round towards an integer. For what I can remember, the use of int for this is discouraged even in Perl (5) documentation, due to the fact that its behaviour is not consistent between positive and negative numbers (it only cuts decimals away).

I don't know if this has been changed in Perl 6, but I think that I'll stick to the library ceil anyway.
