Hexadecimal representation of pi

This is actually the outcome of a game of perl golf. The task was to print a hexadecimal representation of pi, where the digits are not calculated en bloc but one after the other. The longer the program runs the more digits it produces.

However, the algorithm itself is rather obfuscated already and reducing the number of characters for the perl golf resulted in another level of obfuscation. So I thought the obfuscation section would be the right place for it to post anyway.

$|=print 3.2;sub O{8*($@-$_)+(1,4,5,6)[$:]};sub o{(-4,2,1,1)[$:]/O};while($,=++$@){for$:(0..3){ for (0..$@) {for$" (($/=1) ..$_){ ($/*=16) %=O}; $,-=$/ *o}$, -=16** $_*o for-6..- 1}printf "%x",$,* 16%16}

    As you're golfing, there are a few trivial modifications that can save a few characters (update: 4 characters). Omit the semicolons after the sub definitions and for loops, and change ($/*=16)%=O to $/=$/*16%O.

      Thanks for the hints!

      Now that you made me aware of the semicolons after the sub definitions, I am really stunned I didn't realize those myself.

[marto]: FWIW, people shipping things as perl, which aren't strictly perl can cause confusion (Perl and OpenWrt - where to the communities intersect?)
[marto]: cpanm is lighter on resources than cpan, which is handy when working with consumer grade NAS hardware
