# Round a number

=ROUND(number,digits)

To round a number up or down to the nearest specified digit, you can use the ROUND function with a specified number of digits. In the example shown, the formula in cell D6, copied down, is:

=ROUND(B6,C6)

The ROUND function rounds a number to a given number of places. The number of places is set by the number of digits provided in the second argument (*num_digits*). For example, the formulas below round the number 5.86 to 1 and zero places:

In the example shown, we are rounding the values in column B (which are created with the PI function) using the numbers in column B for digits. The formula in cell D6 is

=ROUND(B6,C6)

This tells Excel to take the value in B6 (PI) and round it to the number of digits in cell C6 (4) with a result of 3.1416

In the table, the ROUND function is used to round the same number (PI) to a decreasing number of digits, starting at 4 and moving down past zero to -1. Notice that digits greater than zero round to the right of the decimal point, and digits less than or equal to zero round to the left.
