# How to Use Excel IMPRODUCT Function?

IMPRODUCT Function in Excel: Excel is a spreadsheet program that is developed for WindowsMacAndroid, and iOS. It helps to perform calculations on your PC. The purpose of this software is to do complicated calculations which are difficult to do manually. If you want to get the product of one or more complex numbers, you can use the IMPRODUCT function.

## Explanation of IMPRODUCT Function

• It is one of the built-in functions in Microsoft Excel.
• This function returns the product of one or more complex numbers (1 – 255 complex numbers).
• It will replace the result in the form of a complex number.
• Generally, a complex number is in the form of (X±Yi) or (X±Yj).
• X and Y are real numbers, and i or j is an imaginary number.
• X is a real part, Yi is an imaginary part.
• For example, (2+3i), (6-2i) like that.

## Syntax

• Here, you will see the syntax of the IMPRODUCT function.
• To apply this function on your spreadsheet, you must select a cell and enter the formula in the following format.
• Once you enter the formula, click the button to get the result.

=IMPRODUCT(inumber1, [inumber2], …)

Argument Explanation:

• inumber is a complex number 1.
• inumber 2 is optional and a second Complex number (1 – 255 complex numbers to multiply).
• The product of two complex numbers is calculated as follows:

( a + bi )( c + di )= (ac – bd )(ad+bc)i

Note:
1) You can use the COMPLEX function to convert real and imaginary coefficients to a complex number.
2) If the number is a non-numeric value (letters and special characters), it returns #NUM! Error.
3) Only “i” or “j” is allowed to use in this function, and other values will return #NUM! Error.

## Examples

The following example has shown how it gets the product of one or more complex numbers using this function.

• Initially, you have to open your Excel workbook on your PC and launch the worksheet with data.
• For instance, we have given the input values in the range B3:C6. And we will get the product of them using the IMPRODUCT function.
• Then, you have to enter the formula in the cell as shown below to get the result.
• After entering the formula, you need to click the  button to get the output.
• Once you get the output for the first cell, then you can drag down the cell to the below to get the result of the remaining cells.

## Input that Causes Error

• Only “i” or “j” is allowed to use in this function, other values will return #NUM! Error.
• If the number is a non-numeric value (letters and special characters), it returns #NUM! Error.
