Engineering - IMLOG2 Function
Description
The IMLOG2 function returns the base-2 logarithm of a complex number in x + yi or x + yj text format. The base-2 logarithm of a complex number can be calculated from the natural logarithm as follows −
$$\log_2(x+yi)=(log_2e)\ln(x+yi)$$
Syntax
IMLOG2 (inumber)
Arguments
| Argument | Description | Required/ Optional |
|---|---|---|
| Inumber | A complex number for which you want the base-2 logarithm. | 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, IMLOG2 returns the #NUM! error.
If inumber is a logical value, IMLOG2 returns the #VALUE! Error.
Applicability
Excel 2007, Excel 2010, Excel 2013, Excel 2016
