=IMSUB(inumber1, inumber2)
=IMSUB("1+2i",3)
returns "-2+2i". This example subtracts 3 from the imaginary number "1+2i". The result is "-2+2i" which is a complex number. =IMSUB("3+4i","1+2i")
returns "4i". This example subtracts "1+2i" from the imaginary number "3+4i". The result is "4i" which is a complex number.The IMSUB function subtracts two complex numbers and requires two arguments for successful completion.
