Symptoms
Encountered a problem when we try to use a regex to determine if a decimal is non-negative.
We have used the regex ^[0-9]+.[0-9]+$ against a value 8.00 and it fails at first. When we select the field again and put in the same value, it passes.

Resolution
Smartforms appears to use .NET regular expressions (regex provided) instead of JavaScript (mentioned on the ticket), so regular expressions tested with a JavaScript tester will evaluate differently than those tested with a .NET tester.
Customer use the following Regex to fix the issue:
^d+(.d+){0,1}$
