COMPLEX(RN,IN,S)
- 'RN' is the real number.
- 'IN' is the imaginary number.
- 'S' is the suffix for the imaginary number.
Description
- COMPLEX function converts the real and imaginary coefficients into a complex number.
- A complex number is a number is in the form z = a + bi, where a and b are real numbers and i is the imaginary unit and
- In COMPLEX(RN,IN,SF), here RN is the real part of a complex number,IN is the imaginary part of a complex number and SF is the imaginary unit of a complex number like 'i' or 'j'.
- to mention 'i' and'j' we must use the lower case only
- In a complex number 'z' real part is denoted by Re(z)& imaginary part is denoted by Im(z).
- COMPLEX returns the error value, when RN and IN are non-numeric.
- Suffix 'S' should be either 'i' or 'j', 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.
- COMPLEX(RN,IN,S)
- =COMPLEX(5,2) is 5+2i
- =COMPLEX(5,2,"j") is 5+2j
