bool operator!=(const nml::vec4& lhs, const nml::vec4& rhs)

Return true if the two vec4 are different, else, return false.

The inequality between two vec4 is calculated this way:

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

\((lhs.x \neq rhs.x) or (lhs.y \neq rhs.y) or (lhs.z \neq rhs.z) or (lhs.w \neq rhs.w)\)

Example

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

int main() {
        nml::vec4 a(1.0f, 2.0f, 3.0f, 4.0f);
        nml::vec4 b(3.0f, 2.0f, 4.0f, 5.0f);
        bool c = (a != b);
        std::cout << c << std::endl;

        return 0;
}

Result:

1
