  1. The ROUND function in Excel works by rounding the numbers 1-4 down and rounding the numbers 5-9 up.
  2. You can use the ROUND function in excel for rounding numbers to a specified level of precision. ROUND can be used for rounding to the right or left of the decimal point.
  3. If num_digits is greater than 0, number will be rounded to the specified decimal places to the right of the decimal point. For example, =ROUND (216.55, 1) will round 216.55 to 216.6.
  4. If num_digits is less than 0, number will be rounded to the left of the decimal point (i.e. to the nearest 10, 100, 1000, and so on). For example, =ROUND (16.55, -1) will round 16.55 to the nearest 10 and return 20 as the return value or result.
  5. If num_digits = 0, number will be rounded to the nearest integer (no decimal places). For example, =ROUND (16.55, 0) will round 16.55 to 17.
