IMLN

IMLN(inumber)

Returns the natural logarithm of a complex number.

inumber

The complex number you want the natural logarithm of.

REMARKS

* If "inumber" is not in the form x + yi or x + yj, then #NUM! is returned.
* You can use the IMEXP function to return the exponential of a complex number.
* You can use the LN function to return the natural logarithm of a number.
* You can use the LOG10 function to return the base-10 logarithm of a complex number.
* You can use the COMPLEX function to convert real and imaginary coefficients into a complex number.
