Excel mistakes are like to walking on explosives. You never know when they’ll blow up and create a major commotion. In our posts, we’ve been discussing the most common Excel mistakes and how to quickly solve them.
WHY DOES EXCEL HAVE A #DIV/0 ERROR?
Well, mathematics is the fundamental cause of the #Div/0 mistake. All of us are aware from our high school math textbooks that multiplying any integer by zero is illegal since it is undefined.
The same idea also holds true for Excel. Since it is forbidden to divide any cell value by 0, Excel will indicate this by displaying the error message #Div/0. The majority of users won’t purposefully divide data by zero, nevertheless. You can unintentionally utilise a denominator reference that refers to a null or zero value. This is typically the true reason for the DIV problem in Excel.
The AVERAGE function is yet another important convincing reason. The average function will produce a Div/0 error when used on non-numeric data because the denominator is missing.
Additionally, a Div/0 error will appear if you use an AVERAGEIF or AVERAGEIFS if the function fails to locate even one satisfying condition. similar like previously. There is no denominator that is valid.
How can #DIV/0 errors be fixed in Excel?
Excel’s Div/0 mistake removal process is quite simple. Finding the error is as simple as changing or correcting the denominator that is to blame. Thankfully, unlike the REF error, the #Div/0 error will still show the original formula references that caused the issue.
However, as we previously noted, it is preferable to look at other approaches to handling this mistake if it is brought on by a blank space or an unintentional zero in the reference cell.
Let’s take a quick look at two such techniques.
Errors #Div/0 Trapping IFERROR use
The majority of #Div/0 errors are innocuous since they only highlight a data entry issue. Simply trapping them and displaying a unique error message is more than adequate. Some users might rather have a blank. You are entirely in control.
Simply include your calculations that lead to errors in the IFERROR function as follows:
IFERROR(FORMULA(),”Error Message”) displays the specific message you wish to see when an error occurs, where FORMULA is the formula that caused the issue. If you want it that way, leave it blank.
The formula in this instance will be IFERROR(C3/B3,” Not Found”). IFERROR(C3/B3,””) is the formula if you want a blank space. Drag the appropriate IFERROR formula to the remainder of the range after typing it in the first cell.
All #Div/0 problems, including #N/A, #REF, #VALUE, and #NAME errors, will be caught by this. In other words, if there is no mistake, the FORMULA() result will be shown. If an issue is found, it will either provide a specific error message or nothing at all.
Please be aware that Excel 2007 and later versions are the only ones that support the IFERROR. You must combine the IF and ISERROR functions if you are using an earlier version of Excel. The idea is the same, except now we utilise two functions to check for mistakes rather than just one.
Checking the Denominator for Null and Zero Values
IFERROR is not required if you are using a very basic formula like C3/B3. A straightforward IF statement may be used to quickly determine whether the denominator is incorrect. Simply enter: IF(B3,C3/B3,,”Message”). If necessary, you can substitute a space or 0 for the message.
You may use the following, for instance, to create a blank space:
IF(B3, C3/B3, ” “)
Alternatively, apply the following formula to get a zero:
Although the #Div/0 Excel may not appear to be problematic, it is if you want to use the resulting numbers in subsequent computations. Your other calculations may suffer if these erroneous values are introduced. As a result, it is usually recommended to stop them before they start.
