LibreOffice 6.4 Help
A complex number is a string expression resulting in the form "a+bi" or "a+bj", where a and b are numbers.
If the complex number is actually a real number (b=0), then it can be either a string expression or a number value.
La funció retorna sempre una cadena que representa un nombre complex.
Si el resultat és un nombre complex amb una de les parts (a o b) igual a zero, esta part no es mostra.
The imaginary part is equal to zero, so it is not displayed in the result.
The result is presented in the string format and has the character "i" or "j" as an imaginary unit.
