-=item B<C<r>>
-
-means that all the elements of the map array are either rational numbers or
-the string C<"NaN">, meaning "Not a Number". A rational number is either an
-integer, or two integers separated by a solidus (C<"/">). The second integer
-represents the denominator of the division implied by the solidus, and is
-guaranteed not to be 0. If you want to convert them to scalar numbers, you
-can use something like this:
-
- my ($invlist_ref, $invmap_ref, $format) = prop_invmap($property);
- if ($format && $format eq "r") {
- map { $_ = eval $_ } @$invmap_ref;
- }
-
-Here's some entries from the output of the property "Nv", which has format
-C<"r">.
