Inumber is a complex number for which you want the base-2 logarithm.
- Use COMPLEX to convert real and imaginary coefficients into a complex number.
- If inumber is not in the form x + yi or x + yj, IMLOG2 returns the #NUM! error value.
- The base-2 logarithm of a complex number can be calculated from the natural logarithm as follows:
IMLOG2("3+4i") equals 2.321928 + 1.337804i
