=head1 NAME

Test::Stream::Compare::Number - Compare 2 values as numbers


B<This distribution is deprecated> in favor of L<Test2>, L<Test2::Suite>, and

See L<Test::Stream::Manual::ToTest2> for a conversion guide.


This is used to compare 2 numbers. You can also check that 2 numbers are not
the same.

B<Note>: This will fail if the recieved 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
diagnotics show both values.
