=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.
