How to match float numbers without empty matches

Question

I've custom regex where I match float numbers.

Regex:

/[0-9]*\,?[0-9]*\.?[0-9]*/m

When I tried with string 1,5$+absd1.5a get 10 matches on result where 1 match == 1,5 and 8 match = 1.5. Other matches is empty. How I can match without empty results?
