# Browser and server rules

The InForm application supports rules that run on the browser before a user has submitted data, and rules that run on the server upon submission of new or updated data.

- Browser rules—These rules are primarily for data type checks; for example, to make sure that a float item is entered with the proper number of digits after the decimal place.
- Server rules—These rules can be used for many types of edit checks; for example, to check data ranges, or to calculate or check the value of one item based on the value of another.
