Function name:
ROUND

Category:
Mathematical

Summary:
Rounds a number to the nearest multiple of a specified power of 10.

Syntax:
ROUND(Number[; Count])

Returns:
Returns a real value which is the specified number rounded to the required precision.

Arguments:
Number is a real number, or a reference to a cell containing that number, that is to be rounded.

Count is an integer, or a reference to a cell containing that integer, that is used to specify the precision of the rounding. If Count is omitted, a default value of 0 is assumed. The value of Count is utilized as follows:


 * If Count is a positive integer, then rounding is to the right of the decimal separator. For example, if Count is equal to 1 then numbers are rounded to the nearest multiple of $$\frac{1}{10}\text{th}$$; if Count is equal to 2 then numbers are rounded to the nearest multiple of $$\frac{1}{100}\text{th}$$; and so on.
 * If Count is equal to zero, then rounding is to the nearest integer.
 * If Count is a negative integer, then rounding is to the left of the decimal separator. For example, if Count is equal to -1 then numbers are rounded to the nearest multiple of 10; if Count is equal to -2 then numbers are rounded to the nearest multiple of 100; and so on. The value returned by ROUND will always be an integer when Count is negative.

The following conditions (including errors) may be encountered:


 * If either Number or Count is non-numeric, then ROUND reports a #VALUE! error.
 * If Count is a non-integer value, then it is rounded to the next integer in the direction of 0.

Additional details:

 * This function rounds to the nearest appropriate value, depending on the precision selected. If Number is equidistant from two nearest values, then rounding is away from 0 to the value with the higher magnitude. For example, 7.5 is equidistant from 7 and 8 so that the formula  will return the value 8. Similarly, the formula   will return the value -8.


 * If you obtain unexpected results from ROUND, check the following:


 * Make sure that the number of displayed decimal places is not affected by the setting of the Limit decimals for general number format option in the General Calculations area of the dialog ( on macOS).
 * Access the Numbers tab on the Format Cells dialog ( or equivalent interaction) to make sure that relevant cells do not have formatting applied that affects the number of displayed decimal places.
