The ROUND function is used to reduce a given value to a specific number of decimal places.

The function will round the last number (the rounding digit) up or down depending on the value of the number to the right of the rounding digit.

  • If the value of the number to the right of the rounding digit is less than five, the rounding digit is left unchanged

  • If the value of the number to the right of the rounding digit is five or higher, the rounding digit is raised by one

The ROUND Function's Syntax and Arguments

A function's syntax refers to the layout of the function and includes the function's name, brackets, and arguments.

The syntax for the ROUND function is:

= ROUND ( Number, Num_digits )

Number - the value to be rounded.

Num_digits - the number of decimal places to reduce the above number to.

  2. Click on cell E1 in the worksheet - this is where the function will be located.

  3. Click on the Formulas tab of the ribbon menu.
