in reply to Math::BigInt Newbee question.
When I run that code, I get
$ perl whomany.pl 2 675 Global symbol "$arg2" requires explicit package name at test.pl line 2 +0. Execution of test.pl aborted due to compilation errors.
So I am guessing that the code you pasted is not the code that's actually running. You don't declare $arg2 and are missing ->new in a few places.
Also, bdiv and bmul modify inplace. I believe what you were trying to write is:
Note: Also, to be really correct, you will need to add 1 more CD to the final result to take up the remainder of the data.#!/usr/bin/perl -w use strict; use Math::BigInt; #BigInt KiloByte Unit my $KB = Math::BigInt->new( "1024" ); #BigInt MegaByte Unit my $MB = $KB->copy()->bmul( $KB ); #BigInt GigaByte Unit my $GB = $MB->copy()->bmul( $KB ); print "$KB, $MB, $GB\n"; my $arg1 = Math::BigInt->new( shift ); my $arg2 = Math::BigInt->new( shift ); # arg1 is in GBs my $GBarg1 = $arg1->copy()->bmul( $GB ); # arg2 is in MBs my $MBarg2 = $arg2->copy()->bmul( $MB ); print $GBarg1, " ", $MBarg2, "\n"; # why rc is 0? my ($rc, $rem) = $GBarg1->copy()->bdiv( $MBarg2 ); print "rc is [$rc]\n";
Update: Clean up code a bit
