Long numbers in Excel not displaying properly, how to solve
Excel allows up to 11 digits to be displayed. If the number entered is more than 11 digits, it is automatically expressed in scientific notation. If the number entered is more than 15 digits, all digits starting from the 16th digit are converted to 0 and cannot be recovered. So how to enter long numbers in Excel? Excel supports inputting multiple texts in one cell. You can input long number by displaying long number as text.
In addition to entering long numbers(large numbers), sometimes formulas also return long numbers. How can such a long number exceeding 15 digits be displayed completely? You need to convert numbers to text with function in this case. If long numbers are represented by scientific notation by default when making a document and want to display them all, what should I do? The same method is used to convert numbers to text. You open a text file with long numbers directly in Excel, all long numbers are also represented by scientific notation by default, and numbers exceeding 15 digits are converted to 0, so they cannot be opened directly, you need to import them in Excel.
I, How to enter long numbers in Excel and display them completely
(I) Convert numbers to text with quotation marks(')
1. Select or doubleclick the cell where you want to enter the long numbers, enter a quotation marks('), then enter the 15digit long numbers, and press Enter after the input is completed, all the entered numbers are displayed, they are not automatically expressed in scientific notation, and the preceding quotation marks are automatically hidden; the operation steps are shown in Figure 1:
Figure 1
2. Here, the function of quotation marks is to convert the entered numbers into text. It is through conversion that all numbers are displayed completely.
(II) Set the Formats cell as text
1. Select the cell where you want to enter the long numbers(such as A2), press the shortcut key Ctrl + 1, open the "Format Cells" dialog box, select the "Number" tab, and then Select "Text" on the left, click "OK", set the format of A2 to "Text", enter the long numbers, press Enter, all the numbers to be entered are displayed and no subsequent digits are turned to 0; the steps of the operation process, as shown in Figure 2:
Figure 2
2. If the long numbers are ready, you can directly copy them to the cells formatted as text, so that they will not be displayed incomplete because the number is too long.
II, How to display the results returned by formulas as long numbers in Excel?
1. Doubleclick cell C2, enter the formula =A2*B2, and press Enter to return the result expressed in scientific notation; select C2, move the mouse to the cell fill handle in the bottom right corner of C2, and after the mouse becomes the bold black the plus sign, doubleclick the left button, all the returned results are expressed in scientific notation. Doubleclick C2, change the formula to =TEXT(A2*B2,"0"), press Enter to return a string of long numbers, return the remaining results with the method of doubleclicking the cell fill handle of C2, and they all show the numbers in full; the process steps are shown in Figure 3:
Figure 3
2. Formula description:
A. The formula =A2*B2 is the product of A2 and B2. Since A2 and B2 are relative references to columns and rows, when you drag down, A2 will automatically become A3, A4, etc., and B2 will automatically become B3, B4, etc., so the product of cells below A2 and B2 can be calculated.
B. The formula =TEXT(A2*B2,"0") is used to round and convert the product of A2 and B2 into text. The second argument "0" is used to format, "0" means only integers are retained. The Text function is used to convert numbers, dates, and times into text.
III, Long numbers in excel are cancelled scientific notation(Long numbers not displaying properly in excel)
(I) The method of custom format of cell
1. Select two long numbers in the text file window, press Ctrl + C to copy, click anywhere in the Excel window to go to the window, select cell A1, and press Ctrl + V to paste the two long numbers into A1 and A2 and automatically display in scientific notation.
2. Press Ctrl + 1, open the "Format cells" dialog box, select the "Number" tab, then select "Custom" in the bottom left corner of the dialog box, enter 0 under "Type", and click "OK", then the long numbers are cancelled the scientific notation, and all numbers are displayed, but the last digit of the numbers in A2 has changed from 5 to 0; the operation steps are shown in Figure 4:
Figure 4
Tip: Although it is possible to fully display the numbers represented by scientific notation in a custom cell format, if the long numbers exceeds 15 digits, the digits after the 15th digit are all turned to 0 and cannot be recovered(because Excel has the most 15 digits are allowed), so long digits longer than 15 digits must be converted to text.
(II) Use the "Text to Columns"
1. Select A2:A4, select the "Data" tab, and click the "Text to Columns" in the "Data Tools" group to open the "Convert Text to Columns Wizard" dialog box; select "Delimited" for "Choose the file type that best describles your data", Click "Next"; go to step 2, keep the default option for "Delimiters", click "Next "; go to step 3, select "Text" for "Column data format", and click "Finish", All long numbers expressed in scientific notation are displayed; the operation process steps are shown in Figure 5:
Figure 5
2. This method is the same as the above method. If the number exceeds 15 digits, the digits after 15 digits will be fully converted to 0 and cannot be recovered.
