Dear esteemed Monks, i have a problem which i cannot figure out. this is also in reguards to the whole program/gui that i am making. (yes i know its taing me forever, but what a learning expirience :) )

Anyways, i have made a script that "should" return the percentage of given characters in a file. the file i am trying to find the amount of characters in, is a binary file thats unpacked with 'H*' for its hex representation, then i search this hex for characters. here is the code: 
use File::Slurp;

my $file = read_file("file.bin");
my $data = unpack( 'H*', $file );

my $count =()= $data =~ /ff/g;
my $size = (stat("file.bin"))[7];

my $dec = $count/$size;
my $percentage = ($dec*100);

print "$count\n";
print "$size\n";
print $percentage;

it is returning an almost correct value of 10.65, but that is a little higher than what HxD hex editor reports in statistics... which is 10.43. Also i am pretty sure my math is right, but im not the best mathamagician though, lol

Any help would be appreciated :)
