## How to use the ROUNDDOWN function

The ROUNDDOWN function calculates a number rounded down based on the number of digits to which you want to round the number.

Formula in cell D3:

=ROUNDDOWN(B3, C3)

### Excel Function Syntax

ROUNDDOWN(*number*, *num_digits*)

### Arguments

number |
Required. The value to round. |

num_digits |
Required. A number representing the digit you want to round down to. |

### Comments

The ROUNDDOWN function rounds

- down to the given decimal if num_digit is larger than 0 (zero).
- down to the nearest integer if num_digit is 0 (zero).
- down to the number to the left of the decimal point if num_digit is less than 0 (zero).
