The MROUND worksheet function returns a number that is rounded to a specific multiple. However, MROUND requires that the Analysis ToolPak add-in be installed before the function is available. If you do not want to install the Analysis ToolPak, you can use the ROUND worksheet function instead.
Rounding a NumberTo round a number to the nearest multiple of "x" by using ROUND in Microsoft Excel, use the following syntax:
For example, to round a number to the nearest multiple of 5, enter the following into a worksheet:
=ROUND(<value or reference>/x,0)*x
The result is 15.
A1: 17 B1: =ROUND(A1/5,0)*5
The following formula, which uses the MROUND function, rounds the number 1.58 to the nearest fractional multiple of 0.5:
The result is 1.50.
NOTE: The MROUND function is installed with the Analysis Toolpak add-in. To load this add-in after you install it, click Add-ins on the Tools menu. In the Add-ins dialog box, click to select the Analysis ToolPak check box.
Rounding TimeTo round time to the nearest multiple of "x" by using ROUND in Microsoft Excel, use the following syntax:
Note that you must multiply the time by 24 to convert the time value to its decimal equivalent. In this example, 8:05 becomes the number 8.08333. It is converted back to a time value by dividing by 24 again at the end of the formula.
=ROUND(<value or reference>*24/x,0)*x/24
For example, the following formula, which uses the ROUND function, rounds the time 8:10 to the nearest quarter of an hour or the nearest 15 minutes:
The result is 8:15.
NOTE: You can refer to a cell address instead of using TIMEVALUE("8:05"), as in the following formula:
The following formula, which uses the MROUND function, rounds the time 8:05 to the nearest quarter of an hour or to the nearest 15 minutes:
A1: 8:10 B1: =ROUND(A1*24/0.25,0)*0.25/24
The result is 8:00.
A1: 8:05 B1: =TIMEVALUE(HOUR(A1)&":"&MROUND(MINUTE(A1),15))
