Excel has a maximum precision of 15 significant digits, which means that for any number containing 16 or more digits, such as a credit card number, the last digit is rounded down to zero.<br />
<br />
You can do one of two things:<br />
<br />
1. Use the apostrophe character<br />
For a small set of number codes, you can type an apostrophe character (') in front of the number code and then add back the leading zeros.<br />
<br />
2. Convert the number to text

Hi,<br />
<br />
In Excel, I want to write a 16 number bank account number. So when in custom format using Format Cells, I use 16 0s (0000000000000000), then while I write a bank account number in the cell ending with 9, then last number changes to zero.<br />
<br />
Example: 1234567890123459 changes to 1234567890123450 - why does this happen I don't understand.<br />
<br />
Will appreciate a fast reply.<br />
