Round a number down

We use the ROUNDDOWN function to round a number down, not minding the number being rounded to a specified number of decimal places. We will walk through the process of using the ROUNDDOWN function in simple steps. Figure 1- Results of using the ROUNDDOWN function

General Formula

=ROUNDDOWN(number,num_digits)

• “Number” – number to round down
• “num_digits – the number of decimal places to round down the number.

Formula

=ROUNDDOWN(B4,C4)

Setting up the data

• We will input the numbers to be rounded up in the range: B4:B10
• Next, we specify the number of digits in the range C4:C10
• We will place the results in Column D, which we name “Results.” Figure 2 – Setting up the Data

Applying the Excel ROUNDDOWN function

• We will click on Cell D4
• We will insert the formula below in Cell D4

=ROUNDDOWN(B4,C4) Figure 3 – Applying the ROUNDDOWN function

• We will press the enter key Figure 4- Cell containing a rounded down number

• We will use the fill handle tool to copy the formula into the other cells to get the results. Figure 5-How to use the Excel ROUNDDOWN function

Explanation

The ROUNDDOWN function will always round numbers 1-9 down. This is unlike the standard rounding that rounds numbers less than 5 down. It works like the Excel ROUND function and positive digits will be rounded to the right of the decimal point while zero and negative numbers will be rounded to the left.

Therefore:

• If num_digits is > 0, the number will be rounded to the right of the decimal point
• If num_digits is < 0, the number is rounded down to the left of the decimal.
• If num_digits = 0, the number is rounded down to the left of the decimal point
