Since you don't really need to know what the exact sides are, why not let perl do most of this for you?
use strict;
use Carp;
my ($l, $r, @err) = split /\./, $test;
carp "oops, more than 2 \.'s.\n" if @err;
if ($l) {
if ($r) {
#handle case of rational dollars
} else {
#handle case of integer dollars
}
} else {
carp "oops, we don't even have a dollar!\n";
}
This seems like it'll cover more cases than you currently have (never trust your user) and it seems a bit easier as well...

ps if another monk can spot errors please do so, it's early and i haven't had my coffee yet...
