Engineering - IMDIV Function
Description
The IMDIV function returns the quotient of two complex numbers in x + yi or x + yj text format.
$$IMDIV(z1,z2) = \frac{(a+bi)}{(c+di)}=\frac{(ac+bd)+(bc-ad)i}{c^2+d^2}$$
Syntax
IMDIV (inumber1, inumber2)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Inumber1 | The complex numerator or dividend. | Required |
| Inumber2 | The complex denominator or divisor. | Required |
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 inumber2 is equal to 0, or if either of inumber1, inumber2 is not recognized as a complex number, IMDIV returns the #NUM! error.
If either of inumber1, inumber2 is a logical value, IMDIV returns the #VALUE! Error.
Applicability
Excel 2007, Excel 2010, Excel 2013, Excel 2016
