ROUND function

This article describes the formula syntax and usage of the ROUND function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Office Excel.

Description

The ROUND function rounds a number to a specified number of digits. For example, if cell A1 contains 23.7825, and you want to round that value to two decimal places, you can use the following formula:

=ROUND(A1, 2)

The result of this function is 23.78.

Syntax

ROUND(number, num_digits)

The ROUND function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):

  • number    Required. The number that you want to round.
  • num_digits    Required. The number of digits to which you want to round the number argument.

Remarks

  • If num_digits is greater than 0 (zero), then number is rounded to the specified number of decimal places.
  • If num_digits is 0, the number is rounded to the nearest integer.
  • If num_digits is less than 0, the number is rounded to the left of the decimal point.
  • To always round up (away from zero), use the ROUNDUP function.
  • To always round down (toward zero), use the ROUNDDOWN function.
  • To round a number to a specific multiple (for example, to round to the nearest 0.5), use the MROUND function.
