I’m new to Airtable and among the frustrating things I’ve found is that when I change the display of my currency field from $1.00 to $1, and then back to $1.00, it has wiped out the cents. For example, $1.25 becomes $1, and then $1.00. Permanently.
It should instead store the original full amount and merely change the display of the number. I am certain most users, if not all, would expect it to work this way.
