vec2: nml::vec2& operator+=(const nml::vec2& other)

Add a vec2 to the current vec2.

The sum between two vec2 is calculated this way:

\(\begin{bmatrix} x \\ y \end{bmatrix} + \begin{bmatrix} other.x \\ other.y \end{bmatrix} = \begin{bmatrix} x + other.x \\ y + other.y \end{bmatrix}\)

Example

#include "include/vec2.h"
#include <iostream>

int main() {
        nml::vec2 a(1.0f, 2.0f);
        nml::vec2 b(3.0f, 4.0f);
        a += b;
        std::cout << nml::to_string(a) << std::endl;

        return 0;
}

Result:

[4.000000, 6.000000]
