Engineering - IMEXP Function
Description
The IMEXP function returns the exponential of a complex number in x + yi or x + yj text format. The exponential of a complex number is −
$$e^{(x+yi)}=e^xe^{yi}=e^x(\cos y + i\sin y)$$
Syntax
IMEXP (inumber)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Inumber | A complex number for which you want the exponential. | 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 inumber is not recognized as a complex number, IMEXP returns the #NUM! error.
If inumber is a logical value, IMEXP returns the #VALUE! Error.
Applicability
Excel 2007, Excel 2010, Excel 2013, Excel 2016
