ibanix has asked for the wisdom of the Perl Monks concerning the following question:
Hi monks; thanks for your help with my date formatting question yesterday. Today I find myself needing to round integer values upwards, based on a sliding scale. It looks something like this: As you can tell, the pattern isn't too hard to deduce. I believe I can use log10() to figure out which category I'm in, but what methods do I use to perform rounding operations based on a ruleset like this? Is there something like ceiling() with the ability to define my boundries? Thanks all! ibanix $ echo '$0 & $0 &' > foo; chmod a+x foo; foo;
