Now that I have it working as I had hoped, here is the completed code (with POD) if you are interested.

#!/usr/bin/perl use strict; use warnings FATAL => qw( all ); use Data::Dumper; use List::MoreUtils qw(firstidx apply); use lib 'lib'; use Base::Nifty qw(pretty_number); =head1 Filesize converter This script converts one filesize to another filesize like gigabytes t +o kilobytes and the reverse. There is also a random filesize generator included for fun. =head2 Author(s) Lady_Aleena with lots of help from PerlMonks. =head2 Usage To use this script, please use the following. convert_filesize( size => 10101101, from => 'megabytes', to => 'kb', decimals => 2, base => 1000, ); print $conversion; size is the original size you want to convert and is required. from is the filesize name you want to convert from and is required. to is the filesize name you want to convert to and is required. decimals is the how many decimals you want returned. Conversions from +smaller to larger can lead to a lot of decimals places. The default i +s 0. base is how many of a smaller is in a larger. Some use 1024 as the bas +e while others use 1000. Default is 1024. =head3 from and to For the from and to fields, you do not have to worry about case. byte(s) or bb kilobyte(s) or kb megabyte(s) or mb gigabyte(s) or gb terabyte(s) or tb petabyte(s) or pb exabyte(s) or eb zettabyte(s) or zb yottabyte(s) or yb =head2 Random To use the random generator if you happen to have a secret agent prote +cting a file of a size you don't feel like coming up with, you'd do.. +. my $random_filesize = random_filesize(); You could get anything from a bit to a yottabyte. =cut local $\ = "\n"; my @filesize_names = qw(bit nibble byte kilobyte megabyte gigabyte ter +abyte petabyte exabyte zettabyte yottabyte); # I put the these sizes here just for my information. my %little_filesizes; $little_filesizes{bit} = 1; $little_filesizes{nibble} = $little_filesizes{bit} * 4; $little_filesizes{byte} = $little_filesizes{bit} * 8; # I never know when I'll want a random file size. sub random_filesize { return $filesize_names[rand @filesize_names] } sub make_singular { my $word = shift; $word =~ s/s$//; my @short_sizes = apply {$_ =~ s/^(\w)\w{1,}$/$1b/} @filesize_names; if (grep(/^\L$word\E$/,@short_sizes)) { $word = $filesize_names[firstidx { $_ eq lc $word } @short_sizes]; } return $word; } # from tye: my %hash; @hash{@sizes} = 0..$#sizes; # from MidLifeXis: $result = $original * $units{$inmultiplier} / $unit +s{$outmultiplier} sub convert_filesize { my %opt = @_; # I took out bits and nibbles just to keep me sane. my @filesizes = grep($_ =~ /byte/,@filesize_names); my $from = firstidx { $_ eq make_singular($opt{from}) } @filesizes; my $to = firstidx { $_ eq make_singular($opt{to}) } @filesizes; my $dec = $opt{decimals} ? $opt{decimals} : 0; my $base = $opt{base} ? $opt{base} : 1024; my ($diff,$converted); if ( $from > $to ) { $diff = $from - $to; $converted = $opt{size} * ($base ** $diff); } elsif ( $to > $from ) { $diff = $to - $from; $converted = $opt{size} / ($base ** $diff); } else { $converted = $opt{size}; } my $org_filesize = pretty_number($dec,$opt{size}); my $new_filesize = pretty_number($dec,$converted); return "$org_filesize $opt{from} is $new_filesize $opt{to}"; } print random_filesize; my $conversion = convert_filesize( size => 10101101, from => 'megabytes', to => 'kb', decimals => 2, base => 1000, ); print $conversion;
