How do I use the ROUND function in Excel?

The ROUND function is a useful tool in Excel that allows you to round numbers to a specified number of decimal places. This function can be used in a variety of applications, such as calculating financial figures or simplifying large sets of data.

The basic syntax of the ROUND function is as follows:

=ROUND(number,num_digits)

The 'number' argument is the value you want to round, and the 'num_digits' argument is the number of decimal places you want to round to.

For example, if you have a cell that contains the value '5.789', and you want to round it to two decimal places, you would use the following formula:

=ROUND(5.789,2)

The result of this formula would be '5.79', rounded to two decimal places.

Keep in mind that if the 'num_digits' argument is set to 0, the function will round the number to the nearest whole number. Additionally, if 'num_digits' is a negative number, the function will round the number to the left of the decimal point.
