# FLOOR ### Description `FLOOR` returns the value of the given parameter, always rounded **down** to the nearest whole number. ### Example ``` p is Person FLOOR(p.total_fee) ``` This expression returns the total fee that applies to a person, always rounded down to the nearest whole number, even if the decimal value is .50 or higher. If the total fee for a client comes out at USD 421.68, `CEIL(p.total_fee)` will return USD 421. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
