IMEXP, IMLN, IMLOG10, IMLOG2: Return the exponential, natural log, log (base 10) and log (base 2) of a complex number.IMSIN, IMCOS, IMTAN, etc.: Return the sine, cosine, tangent, etc.IMSUM, IMSUB, IMPRODUCT, IMDIV: Return the results of complex number addition, subtraction, multiplication, and division.This is equivalent to the magnitude of the vector. IMABS: Returns the absolute value of a complex number.But Microsoft includes many more useful functions for complex number calculations: If this is where Excel’s complex number capability stopped, it would be a huge disappointment. However, for most of us this can be omitted and the suffix will default to “i”.Īs an example, entering the following equation in Excel:Ĭonversely, the real and imaginary components of a complex number can be extracted using the IMREAL and IMAGINARY functions, respectively: You can use this optional argument to change the suffix from “i” to “j” if you wish. is the letter appended to the imaginary component of the complex number. I_num is the imaginary part of the complex number Real_num is the real part of the complex number The function is “ COMPLEX” and its syntax is as follows: The first, and most fundamental, complex number function in Excel converts two components (one real and one imaginary) into a single complex number represented as a+bi. ![]() Once turned on, these functions reside in the “Engineering” category of Excel functions. To gain access to them, first enable the Analysis Toolpak Add-In. Microsoft does not automatically expose the complex number functions in default Excel installations. How to Enable Complex Number Calculations in Excel There is built-in capability to work directly with complex numbers in Excel. Fortunately, though, you don’t have to run to another piece of software to perform calculations with these numbers. In some branches of engineering, it’s inevitable that you’re going to end up working with complex numbers.
