so when i do the print (&a-&b) which gets me a 1, that means that the values were in the heap, and when i do the print(c-d), c and d were in the stack.
but why does values in the heap have a different arithmetic then the values in the stack?

Heap::Elem::NumRev(3pm) 				User Contributed Perl Documentation				   Heap::Elem::NumRev(3pm)

NAME
Heap::Elem::NumRev - Reversed Numeric Heap Elements SYNOPSIS
use Heap::Elem::NumRev( NumRElem ); use Heap::Fibonacci; my $heap = Heap::Fibonacci->new; my $elem; foreach $i ( 1..100 ) { $elem = NumRElem( $i ); $heap->add( $elem ); } while( defined( $elem = $heap->extract_top ) ) { print "Largest is ", $elem->val, " "; } DESCRIPTION
Heap::Elem::NumRev is used to wrap numeric values into an element that can be managed on a heap. The top of the heap will have the largest element still remaining. (See Heap::Elem::Num if you want the heap to always return the smallest element.) The details of the Elem interface are described in Heap::Elem. The details of using a Heap interface are described in Heap. AUTHOR
