Engineering - IMPRODUCT Function
Description
The IMPRODUCT function returns the product of 1 to 255 complex numbers in x + yi or x + yj text format. The product of two complex numbers is −
$$(a+bi)(c+di)=(ac-bd)(ad+bc)i$$
Syntax
IMPRODUCT (inumber1, [inumber2] ...)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Inumber1 | 1 to 255 complex numbers to multiply. | Required |
| [inumber2], … | 1 to 255 complex numbers to multiply. | Optional |
Notes
Complex Numbers in Excel are simply stored as text.
When a text string in the format "a + bi" or "a + bj" is supplied to one of Excel's built-in Complex Number Functions, this is interpreted as a complex number.
The complex number functions can accept a simple numeric value, as this is equivalent to a complex number whose imaginary coefficient is equal to 0.
Use COMPLEX to convert real and imaginary coefficients into a complex number.
If any of the inumber arguments is not recognized as a Complex Number, IMPRODUCT returns the #NUM! error.
If any of the inumber arguments is a logical value, IMPRODUCT returns the #VALUE! error.
Applicability
Excel 2007, Excel 2010, Excel 2013, Excel 2016
