How to Use IMSUM in Google Sheets in 2020?

IMSUMReturns the sum of a series of complex numbers or cells or both.

Sample Usage

IMSUM(A2:A100)

IMSUM(“1+2i”,3,”4i”)

IMSUM(“1+2i”,”3+5i”,A2:A50)

Syntax

IMSUM(value1, [value2, …])

value1 – The first complex number or range to add together.
value2, … – [ OPTIONAL ] – More complex numbers or ranges to add to value1.

Notes

The sum of two complex numbers is defined as follows:

(a+bi) + (c+di) = (a+c) + (b+d)i

You can sum complex numbers only if they have the same suffix (i or j). For example, you can’t do IMSUM(“4+3i”, “1+2j”).
