nml::vec4 operator*(nml::vec4 lhs, const float rhs)

Return a vec4 that is the product between a vec4 and a scalar.

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

\(\begin{bmatrix} lhs.x \\ lhs.y \\ lhs.z \\ lhs.w \end{bmatrix} * rhs = \begin{bmatrix} lhs.x * rhs \\ lhs.y * rhs \\ lhs.z * rhs \\ lhs.w * rhs \end{bmatrix}\)

Example

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

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

        return 0;
}

Result:

[3.000000, 6.000000, 9.000000, 12.000000]
