# XL: Rounding Numbers and Time to Specified Multiples

This article has been archived. It is offered "as is" and will no longer be updated.
##### SUMMARY
The MROUND worksheet function returns a number that is rounded to aspecific 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 Number

To round a number to the nearest multiple of "x" by using ROUND inMicrosoft Excel, use the following syntax:
`   =ROUND(<value or reference>/x,0)*x				`
For example, to round a number to the nearest multiple of 5, enter thefollowing into a worksheet:
`   A1: 17     B1: =ROUND(A1/5,0)*5				`
The result is 15.

The following formula, which uses the MROUND function, rounds the number1.58 to the nearest fractional multiple of 0.5:
`   =MROUND(1.58,0.5)				`
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 Time

To round time to the nearest multiple of "x" by using ROUND in MicrosoftExcel, use the following syntax:
`   =ROUND(<value or reference>*24/x,0)*x/24				`
Note that you must multiply the time by 24 to convert the time value to itsdecimal equivalent. In this example, 8:05 becomes the number 8.08333. It isconverted back to a time value by dividing by 24 again at the end of theformula.

For example, the following formula, which uses the ROUND function, roundsthe time 8:10 to the nearest quarter of an hour or the nearest 15 minutes:
`   =ROUND(TIMEVALUE("8:10")*24/0.25,0)*0.25/24				`
The result is 8:15.

NOTE: You can refer to a cell address instead of using TIMEVALUE("8:05"), as in the following formula:
`   A1: 8:10   B1: =ROUND(A1*24/0.25,0)*0.25/24				`
The following formula, which uses the MROUND function, rounds the time 8:05to the nearest quarter of an hour or to the nearest 15 minutes:
`   A1: 8:05   B1: =TIMEVALUE(HOUR(A1)&":"&MROUND(MINUTE(A1),15))				`
The result is 8:00.
