WorksheetFunction.ImLog2 (Excel)
Returns the base-2 logarithm of a complex number in x + yi or x + yj text format.
Use the Complex method to convert real and imaginary coefficients into a complex number. The base-2 logarithm of a complex number can be calculated from the natural logarithm as follows:
ImLog2 (Arg1)
Arg1: Inumber - a complex number for which you want the base-2 logarithm.
Dim strImLog2 As String
