# Trunc Truncates the input value to the specified number of digits or decimal places. ### Usage ``` Trunc(number, [digits]) ``` **number** (required) The number to be truncated **digits** \[optional] The number of decimal places to which to round. Defaults to 0.\ If "digits" value is negative, the function will return an integer with that many least-significant digits zeroed (see example 4 below). ### Examples (1) Returns 5.24 ``` Trunc(5.2463, 2) ``` (2) Returns 5. ``` Trunc(5.678) ``` (3) Truncates the value in each row of the input column to 3 decimal places. ``` Trunc([Cost], 3) ```

(4) Rounds the input number down and replaces its last 2 digits with 0s. A negative "digits" value returns an integer with that many least-significant digits zeroed. ``` Trunc([Cost], -2) ```
