The IMLOG10 function returns the common logarithm (base 10) of a complex number in x + yi or x + yj text format
The IMLOG10 function syntax has the following arguments:
- Inumber Required. A complex number for which you want the common logarithm
Example: Let’s look at some Excel IMLOG10 function examples and explore how to use the IMLOG10 function as a worksheet function in Microsoft Excel:
Based on the Excel spreadsheet above, the following IMLOG10 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, IMLOG10 returns the #NUM! error.
- If inumber is a logical value, IMLOG10 returns the #VALUE! error
- The common logarithm of a complex number can be calculated from the natural logarithm as follows:
