Operators

Operator overloading

in C# operators can be overloaded, which is not supported in Typescript. To mimic this behaviour, we use a convention based approach, along with some helper methods.

Resulting in this kind of coding C# sample

var P1 = new Point(1,1);
var P2 = new Point(3,3);
var P = P1 + P2;

In Typescript

var P1 = new Point(1,1);
var P2 = new Point(3,3);
var P = Ops.Add(P1 , P2);

Example

An operator overload in C#

public static Complex operator +(Complex c1, Complex c2) 
  {
     return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
  }

An implementation in Typescript

public static op_Addition(c1 : Complex, c2: Complex) : Complex
  {
     return new Complex(c1.real + c2.real, c1.imaginary + c2.imaginary);
  }

There are a couple of operator groups

• Unary operators
• Binary operators
• Explicit
• Implicit

op_Incerement op_Decrement

Binary operators

Use the following naming conventions to

+, -, *, /, %, &, |, ^, <<, >>

• op_Addition
• op_Substraction
• op_Multiplication
• op_Division
• op_Modulus
• op_GreaterThan
• op_GreaterThanOrEqual
• op_LessThan
• op_LessThenOrEqual
• op_And
• op_Or
• op_Xor
• op_RightShift
• op_LeftShift
