One of Engineering Function offered by Excel is the IMNL function. This makes the complex number return to its natural algorithm.

The syntax or series of arguments of the IMNL function is IMNL(inumber). In this argument, the inumber refers to a complex number. These complex numbers are already stored in Excel as text. A complex number is interpreted when on the built-in complex number functions of Excel a text string is provided. The imaginary coefficient of complex numbers is zero which means that these numbers can also accept simple numeric values.

You can also view the on the Formulas tab by selecting Formula Auditing group and clicking on the Show Formulas button.

An error on the value which is #VALUE! will occur when the inputted argument on the inumber is not known as a real or imaginary number. Also, if the error result of #NAME? Will appear just follow the steps bellow.

Before being able to use this function first, enable the Analysis ToolPak in Excel. You can do this selecting the Tools and on the drop-down menu select Add-Ins. The window for Add-Ins will pop up then select Analysis ToolPak and hit OK. This process is for Excel 2003, for Excel 2007 and 2010 first select on the spreadsheet select the Excel Options.
