First, you don't have to backwhack (escape) the '.' character when it appears inside of a character class.

Next, [0-9] is the same as \d.

Third, the non-capturing parens are not helping you.

Boil that down and you get: 

print "$1\n" if $number =~ m/
                              ^(
                                [\d.-]*
                                \d
                                [\d.-]*
                              )$
                            /x;

Oh, forgot to mention; the /x modifier helps to keep things clean and tidy looking.

If you really want it golfed, how about this: 

$number =~ /^([\d.-]*\d[\d.-]*)$/ and print "$1\n";
