( #3333=superdoc: print w/replies, xml ) Need Help??

This is not a bug

Perl has magic increment operator, it works on strings

Perl not have magic decrement operator, so string is turned into a number

inf looks like a string so it is a string, not a number, use int to force numification

$ perl -MData::Dump -e " $f = inf; dd $f; $f--; dd $f; " "inf" 1.#INF $ perl -MData::Dump -e " dd int inf " 1.#INF $ perl -MData::Dump -e " dd int Infinity " 1.#INF

perlnumber, perldata, 2010 :) Infinity and Inf?
