+=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.
