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

Substract a vec2 from the current vec2.

The difference 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(4.0f, 6.0f);
        nml::vec2 b(3.0f, 4.0f);
        a -= b;
        std::cout << nml::to_string(a) << std::endl;

        return 0;
}

Result:

[1.000000, 2.000000]
