Complex numbers

Disclaimer: I'm a first year student, and i have no idea what i'm doing. In addition, the variables are named with a mix of French and English language.

The namespace is "Complex" and the class is "Complex" if you want to define an object variable you type:

Complex.Complex z = new Complex.Complex();

How to use

Constructors

use the "Complex()" or "Complex(double x,double y)" to define an object (Complex) variable. Example

Complex z = new Complex(); // real_number=0 and imaginary_number = 0

or

Complex z = new Complex(5,1.5); //real_number = 5 and imaginary_number=1.5

Return the real or the imaginary number

the class stores these 2 numbers as attributes.

Complex z = new Complex(5,1.5);
Console.WriteLine($"{z.reel} , {z.imaginaire}i");
/*Output
5, 1.5i */

Converting to string

the class overrides ToString() method, this means you can print the object or convert it into a string without special code.

Complex z = new Complex(1,1);
Complex z1 = new Complex(1,-2);
Console.WriteLine(z);
Console.WriteLine(z1);
/*Output:
1+1i
1-2i */

Algebraic operations

Basic "z+z1+..." will return the sum of 2/multiple Complex objects in a Complex type. You can add (+), subtract(-), multiply(*), divide (/), turn value negative (-z).

Complex z = new Complex(1,1);
Complex z1 = new Complex(1,-2);
Console.WriteLine(z+z1);
/*Output:
2-1i */

Argument method (z.Arg(string x="rad"))

using Math.Atan() to discover the argument. the method takes 2 string inputs: "rad" to return a radiant unit (Default). "deg" to return a degree unit. typing any other string will throw an ArgumentException(). Disclaimer: the result returns an answer from -pi/2 to pi/2 (not including).

Complex z = new Complex(1,1);
Complex z1 = new Complex(2,5);
Console.WriteLine(z.Arg("deg"));
Console.WriteLine(z1.Arg());
/*Output
45
1.1902899496825317 */
