Re^2: Generating Visually Distinct Colors

Um, what's with that ceil() function? int($x+2)? I'd feel much safer with

sub ceil (Num $x) { $x == int($x) ?? $x :: int($x+1) }

I'm pretty sure that's the appropriate P6 code.

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. Flavio -- Don't fool yourself.	[reply] [d/l] [select]

Yes, I use `ceil()`, I was commenting on the very bizarre P6 ceil-equivalent. _____________________________________________________ Jeff `japhy` Pinyan, P.L., P.M., P.O.D, X.S.: Perl, regex, and `perl` hacker How can we ever be the sold short or the cheated, we who for every service have long ago been overpaid? ~~ Meister Eckhart	[reply]
