Note:

  • 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: IMLOG10 Function in Excel 2 - How to use IMLOG10 Function in Excel
