GETREALORCOMPLEX (x,y)


  • and are any real numbers .


Description

  • This function converts the real and imaginary numbers 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 squaring it gives a negative result.
  • For e.g. {-4}^2 =16. 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 , is the real part of the complex number, is the imaginary part of the complex number.
  • Here suffix value is considered as ""i"".
  • This function returns the error value, when real and imaginary are non-numeric.
  • 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.

Examples

  1. GETREALORCOMPLEX(9,3) = 9+ⅈ3
  2. GETREALORCOMPLEX(12,-90) = 12-ⅈ90
  3. GETREALORCOMPLEX(5.2,-3.1) = 5.2-ⅈ3.1
  4. GETREALORCOMPLEX(-11,-12) = -11-ⅈ12
