In this post, you will learn about the *ROUNDDOWN Function* in Excel, how to use it in – with the excel spreadsheets.

This function is similar to the Round function, but this function rounds down the number to the given number of integers.

**Syntax**

**=ROUNDDOWN(number, num_digit)**

This syntax has two arguments

**number**– This holds the number to be round down**num_digit**– This holds the number of digits that you want to round off the number.

## How does the ROUNDDOWN Function work?

- The function is mostly used when working with
**decimal numbers**. - To start with, enter the numbers and the value of the second argument in the excel sheet. In a new cell enter the
**syntax**and highlight the cells to insert them in the syntax.

- Press enter to display the answer and use the fill handle to apply the function to the rest of the data.
- To round off the number towards the decimal point, use
**positive**numbers in the num_digit argument. For example

=ROUND(a, 1) rounds up the number to 1 number after the decimal point

=ROUND(b, 2) rounds up the number to 2 numbers after the decimal point

**Negative**numbers are used in the num_digit argument to round down the number towards a whole number. For example

=ROUND(a, -1) rounds up the number to the nearest 10.

=ROUND(b, -2)rounds up the number to the nearest 100.

## Additional Points

- The syntax does not accept
**non – numeric**values and returns an error. - This function is one of the different Rounding functions in Excel.
- If the number is already round off the function does not take place.
