Numeric Text Field - Display "Nothing" instead of 0

Is there a way to format a numeric text field to display a blank or nothing when set to zero?

I’m using this to clear the client tag

value = u''
system.tag.write('[client]Form Data/CurUser', value)

Not on the numeric text field, no - but you could use a formatted text field with a numeric regex pattern, set to not allow invalid text:

Then you’ll probably want a custom property on the text field that turns the text property into an integer or long.
