Returns the common logarithm (base 10) of a complex number in x + yi or
x + yj text format.

Inumber is a complex number for which you want the common 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, IMLOG10 returns the #NUM! error value.
- The common logarithm of a complex number can be calculated from the natural logarithm as follows:
IMLOG10("3+4i") equals 0.69897 + 0.402719i
