Re: Blankety-Blank Blanks and Zeros, etc.

One thought:

print +("A float: ",
        $root_beer? sprintf("%12.4f", $root_beer) : $"x12,
        $/);
[download]

(And that's the first time I've seen someone stick $/ inside a double-quoted literal. I use $/ a lot, but I use \n if I'm already in the string literal.)

Why not just switch out the format? `printf +($root_beer ? "%12.4f" : " "x12)."\n", $root_beer;` [download] That's what I'd do if I didn't care too much about maintainability. Of course, the correct way to do it is something like this: `if ($root_beer) { printf "%12.4f\n", $root_beer } else { print " "x12 . "\n"; }` [download] Or any way that you consider more readable. Where "readable" means that you can look at it 6 months later without thinking, "what the hell was I thinking when I wrote this?" :-) duff	[reply] [d/l] [select]
