IMSUM(inumber1, [inumber2], ...)
=IMSUM("1+2i",3)
returns "4+2i". This function sums the imaginary number 1+2i with the real number 3, resulting in the imaginary number 4+2i.=IMSUM("3+4i","1+2i")
returns "4+6i". This function sums the imaginary numbers 3+4i and 1+2i, resulting in the imaginary number 4+6i.The IMSUM function is used to calculate the sum of two or more complex numbers expressed as x + yi or x + yj. The COMPLEX function can be used to create complex numbers from real and imaginary parts.
