I'd like to constrain user input in a decimal field (esri type double) to look like -0.123. That is: either negative or positive, one digit before and 3 digits after the decimal.
I've got the following regular expression as a constraint:
This works, except it won't allow a number like -1.100
The last digit has to be non-zero. If I switch the type of the field to text, it evaluates correctly, but that makes for a much less nice keyboard input on the ipad for the user. I would like to keep the numeric keyboard.
Any ideas? I'm fine with allowing -1 or -1.1 but don't want to allow 100. I would prefer that the user have to type all 3 digits after the decimal. I prefer to have them type the 0 before the decimal if the value is less than 1, but that's negotiable as well.
