The regex matches ".1" that looks stange.
What about:
^\d+(\.\d+)?$
If anyone needs sign information:
^[+-]?\d+(\.\d+)?$
will do the job.

I altered yours a bit to allow for negative entries:
(^(-)?\d*\.?\d*[0-9]+\d*$)|(^[0-9]+\d*\.\d*$)
I tried many other expressions that allow negative entries in addition to other fancy things but I liked your cleaner approach here. Thank you.
