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.
