Such boring limitations, as previously noted. But monstrously large floating points and regexes? Bah. It is simple enough to compute directly using boringly small integers:

#!/usr/bin/perl -w use strict; my( $num, $den )= ( 1, 7, @ARGV )[2&@ARGV,-1]; my $rem= $num % $den; my %seen; my $rep= ''; while( 1 ) { $rem *= 10; last if exists $seen{$rem}; $seen{$rem}= length( $rep ); $rep .= int( $rem / $den ); $rem %= $den; } substr( $rep, 0, $seen{$rem} )= ''; print "$num / $den = ...$rep\n";

Sample runs:

$ perl 97 1 / 97 = ...010309278350515463917525773195876288659793 814432989690721649484536082474226804123711340206185567 $ perl 2 97 2 / 97 = ...020618556701030927835051546391752577319587 628865979381443298969072164948453608247422680412371134
