The IMLOG2 function returns the base-2 logarithm of a complex number in x + yi or x + yj text format
The IMLOG2 function syntax has the following arguments:
- Inumber: Required. A complex number for which you want the base-2 logarithm
Example: Let’s look at some Excel IMLOG2 function examples and explore how to use the IMLOG2 function as a worksheet function in Microsoft Excel:
Based on the Excel spreadsheet above, the following IMLOG2 examples would return:
- 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.
- The base-2 logarithm of a complex number can be calculated from the natural logarithm as follows:
