Friends,

I have never used Math::BigInt before. So I came up with an excuse to write a script that would use it. I wanted to write a simple script that would tell me how many CDs would be needed to hold X Gigabytes of data. Here's the script ... 

#!/usr/bin/perl -w
use strict;
use Math::BigInt;

#BigInt KiloByte Unit
my $KB = Math::BigInt ( "1024" );

#BigInt MegaByte Unit
my $MB = Math::BigInt ( $KB->bmul( $KB ) );

#BigInt GigaByte Unit
my $GB = Math::BigInt ( $MB->bmul( $KB ) );

my $arg1 = Math::BigInt->new( shift );

# arg1 is in GBs
my $GBarg1 = Math::BigInt->new( $arg1->bmul( $GB ) );

my $arg2 = Math::BigInt->new( shift );

# arg2 is in MBs
my $MBarg2 = Math::BigInt->new( $arg2->bmul( $MB ) );

# why rc is 0?
my $rc = $GBarg1->bdiv( $MBarg2 );
print "rc is [$rc]\n";

When I run this I get the output of: 
$ ./whomany.pl 2 675
rc is [0]

What am I doing wrong here?

Thanks

update: Fixed typo (missing my $arg2) pointed out by Paladin.
