IMLN
IML Return the natural logarithm of a complex number in x+yi or x+yj text format with the IMLN
function.
=IMLN(inumber)
The IMLN function is found only if the Analysis Toolpak is installed. In addition it must be
turned on in the Add-Ins from the Tools menu. The example in Figure 5.26 shows the Natural
Logarithm of the complex numbers.
INUMBER The complex number you want the logarithm for.
The natural logarithm for the complex number is
where
See the COMPLEX function earlier in this chapter for obtaining the complex number of real and
imaginar y coefficients.

Returns the natural
logarithm of complex
numbers x+yi or x+yj
in text format.
IMLOG10
IMLOG10 returns the common logarithm (Base 10) of a complex number in x+yi or x+yj text
format.
