The point isn't what this JAPH does, but how it does it. Of course that's nearly always the case with these things, isn't it? ;) This was inspired by a recent Perlmonks discussion on rounding numbers without printf, though it has nothing at all to do with numbers, printf, or rounding. 

require 5.8.0;$o="Just_another_Perl_Hacker";open$o,">",\$s;select
$o;for($^){y$_$ $;s%....$%.\n%;die$_}

This JAPH requires Perl 5.8.0 or later to work properly.

Update: This JAPH uses a feature in Perl 5.8.0 or later that works differently in pre-5.8.0 Perl implementations. With Perl 5.8.0 or later, an in-memory file is created. In pre-5.8.0 Perls, a physical file is created. I have modified the script with the "require 5.8.0" directive to prevent this behavior, after investigating why Anonymous Monk's followup determined that the script still ran under pre-5.8.0 versions.
