Kommentarer

Operatorn Addition tillåter att du utför tilläggsåtgärder som omfattar komplexa tal. Den aktiverar kod, till exempel följande:

Complex c1 = new Complex(1.2, 2.3);
Complex c2 = new Complex(2.1, 3.2);
Complex c3 = c1 + c2;

let c1 = Complex(1.2, 2.3)
let c2 = Complex(2.1, 3.2)
let c3 = c1 + c2

Dim c1 As New Complex(1.2, 2.3)
Dim c2 As New Complex(2.1, 3.2)
Dim c3 As Complex = c1 + c2

Om tillägget resulterar i ett spill i antingen den verkliga eller imaginära komponenten är värdet för komponenten antingen Double.PositiveInfinity eller Double.NegativeInfinity.

Språk som inte stöder anpassade operatorer kan anropa Add motsvarande grupp med metoder i stället.

De Addition operatorer som tar emot en dubbel är effektivare än de operatorer som tar emot två komplexa tal.
