COMPLEXNUM(real,imaginary,suffix)


  • is the real part of the complex number.
  • is the imaginary part of the complex number.
  • is the imaginary unit of the complex number.

Description

  • COMPLEXNUM function converts the real and imaginary coefficients into a complex number.
  • A complex number is a combination of a real and an imaginary number.
  • A number which is positive or negative, rational or irrational or decimals are called real numbers.
  • An Imaginary number is a number that when squring it gives a negative result.
  • For e.g.  . Because a negative times a negative is positive.
  • A complex number is a number is in the form  , where   and   are real numbers and   is the imaginary unit. Where  
  • In  , here   is the real part of the complex number,   is the imaginary part of the complex number and   is the imaginary unit of a complex number like   or  .
  • To mention   and  , we must use the lower case only
  • In a complex number   real part is denoted by   & imaginary part is denoted by  .
  • COMPLEXNUM returns the error value, when   and   are non-numeric.
  •   should be either   or  , otherwise it shows error value.
  • A Complex number whose real part is zero is said to be purely imaginary.
  • A Complex number whose imaginary part is zero is a real number. In that cases we have to assign '0' for that part.
  1. =COMPLEXNUM(5,2) gives  
  2. =COMPLEXNUM(5,2,["j"]) gives  

ZOS

  • The syntax is to calculate COMPLEX in ZOS is  
  •   is the real part.
  •   is the imaginary part.
  •   is imaginary unit which is either "i" or "j".
  • E.x: COMPLEXNUM(-1..1,10..11,"j")
