I have a Text field value of “0.7550000000”. If I convert the field to Number type, it gets displayed in the Data tab as 0.755, hiding the trailing zeroes. if I convert the field back to Text type, the value becomes “0.7550000000” again.
It’s confusing and unexpected when the Data tab does not transparently display the actual stored values, somewhat in the same vein as this DateTime Localization issue where dates get converted to local timezone for display in Data tab (not sure if this behaviour has been discontinued, I hope so!)
