oct(0b & really huge binary) ... "integer overflow in binary number&quo

[SparceMatrix]

I am doing some scripts that work with huge matrices having only ones and zeros in them. As a way of tracking unique rows, I take a row and run it through "oct" and then fool with the array of numbers I get. It worked like a charm for some small matrices, but now that I'm getting row numbers past 100, I'm getting errors, "Integer overflow in binary number".

If this is an unavoidable limitation, is there maybe another way of crunching those rows to sort out the unique ones?

Here is some code I fooled around with to see what was going on.

#!/usr/bin/perl
print oct "0b11111111111111111111111111111";
print "\n";
$MyHugeString = "0b" . "1" x 100;
print oct $MyHugeString;

You can identify unique rows with a hash

my %uniq;

while (<>) {
   chomp;
   $uniq{$_}++;
}

print join("\n", keys %uniq);
