vec4: nml::vec4& operator*=(const float other)

Multiply the current vec4 by a scalar.

The product between a vec4 and a scalar is calculated this way:

\(\begin{bmatrix} x \\ y \\ z \\ w \end{bmatrix} * other = \begin{bmatrix} x * other \\ y * other \\ z * other \\ w * other \end{bmatrix}\)

Example

#include "include/vec4.h"
#include <iostream>

int main() {
        nml::vec4 v(1.0f, 2.0f, 3.0f, 4.0f);
        v *= 2.0f;
        std::cout << nml::to_string(v) << std::endl;

        return 0;
}

Result:

[2.000000, 4.000000, 6.000000, 8.000000]
