The MROUND function rounds a number to the nearest given multiple. The multiple to use for rounding is provided as the significance argument. If the number is already an exact multiple, no rounding occurs and the original number is returned. You can use MROUND to round prices, times, instrument readings or any other numeric value.
In the example shown, we are using MROUND to round the price in column B using the multiple in column C. The formula in cell D6, copied down the table, is:
This tells Excel to take the value in B6 ($63.39) and round it to the nearest multiple of the value in C6 (5). The result in D5 is $65.00, since 65 is the nearest multiple of 5 to 63.39. In the following rows of the table, the same number is rounded using different multiples.
