Engineering - IMSUM Function
Description
The IMSUM function returns the sum of two or more complex numbers in x + yi or x + yj text format. When adding complex numbers, the real and imaginary coefficients are added separately i.e., the equation to find the sum of two complex numbers a+bi and c + di is −
(a + bi) + (c + di) = (a + c) + (b + d)i
Syntax
IMSUM (inumber1, [inumber2] ...)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Inumber1 | 1 to 255 complex numbers to add. | Required |
| inumber2... | 1 to 255 complex numbers to add. | 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, IMSUM returns the #NUM! error.
If any of the inumber arguments is a logical value, IMSUM returns the #VALUE! Error.
Applicability
Excel 2007, Excel 2010, Excel 2013, Excel 2016
