Hi ks,

Formatting complex numbers in Excel is pretty easy. You can use the "Number Format" feature to change the number of digits displayed after the decimal point.

Here are the steps to format complex numbers in Excel:

1. Select the cell(s) containing the complex number(s) you want to format.
2. Right-click on the selected cell(s) and choose "Format Cells" from the context menu.
3. In the "Format Cells" dialog box, select the "Number" tab.
4. In the "Category" list, select "Number".
5. In the "Decimal Places" field, enter the number of digits you want to display after the decimal point.
6. Click "OK" to apply the formatting.

Once you have done this, the complex numbers will be displayed with the specified number of digits after the decimal point.
