gunzip stdin stream? I have a convenient way to open possibly gzip'ed files: open(F, ($f =~ m/\.gz$/) ? "gunzip -c $f |" : "$f"); So, if the file name ends in .gz I send it through gunzip. So far, so good. (I don't want to use the PerlIO:Gzip module because it's not installed by default, so it's a hassle.) But now, my script ... 24 Jan 2006 11:40

Perl - Get Two Decimals Hi all, I was wondering if it is possible in perl to get a number to have exactly two decimal places (like xx.xx). I read about Number::Format, but that is not available for me to use.
