=head1 NAME
Test2::Compare::Number - Compare two values as numbers
=head1 DESCRIPTION
This is used to compare two numbers. You can also check that two numbers are not
the same.
B<Note>: This will fail if the received value is undefined. It must be a number.
B<Note>: This will fail if the comparison generates a non-numeric value warning
(which will not be shown). This is because it must get a number. The warning is
not shown as it will report to a useless line and filename. However, the test
diagnostics show both values.
