Creating and adding complex numbers

Creates complex numbers of type std.math.Complex. Both the real and imaginary part of the complex number must be of the same type.

Performing mathematical operations on complex numbers is the same as on built in types: the numbers in question must be of the same type (i.e. floats or integers).

const std = @import("std");
const print = std.debug.print;
const expectEqual = std.testing.expectEqual;
const Complex = std.math.Complex;

pub fn main() !void {
    const complex_integer = Complex(i32).init(10, 20);
    const complex_integer2 = Complex(i32).init(5, 17);
    const complex_float = Complex(f32).init(10.1, 20.1);

    print("Complex integer: {}\n", .{complex_integer});
    print("Complex float: {}\n", .{complex_float});

    const sum = complex_integer.add(complex_integer2);

    try expectEqual(sum, Complex(i32).init(15, 37));
}
