Rounds a number down to the specified number of digits.

## Usage

RoundDown(number, [digits])

**number** (required) The number to be rounded.

**digits** [optional] The number of decimal places to which to round.

If "digits" value is negative, the function will return an integer with that many least-significant digits zeroed (see example 4 below).

## Example

(1) Returns 3.14

RoundDown(3.141, 2)

(2) Returns -6.255.

RoundDown(-6.25417, 3)

(3) Rounds the value for each row in the input column down. Numbers are rounded by 2 digits.

RoundDown([Cost], 2)

(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.

RoundDown([Cost], -2)
