The IMLN () is an engineering function which takes ‘inumber’ as an argument and returns the natural logarithm of a complex number in the text format of x+yi or x+yj.
Formula:
=IMLN(inumber) In the above syntax, the inumber denotes the complex number for which you want to find the natural logarithm.
