How to validate number field using regular expression check ?

[Vikrant Yadav]

I want to validate number field using regular expression check so that user can't enter value 0.

I want users to enter greater than value 0. What expression do i need to put.

If it's just an integer field, then the expression:

^[1-9]\d*$

should work

Dan, what is recommendation IF Jira keeps adding a .0 to the end of the integer.

Getting error message 1.0 does not match...  We only added the value of 1

@Jeff Pittman- Did you ever figure out the solution for the decimal that they force?
