bool operator==(const nml::vec4& lhs, const nml::vec4& rhs)
Return true if the two vec4 are identical, else, return false.
The equality between two vec4 is calculated this way:
\(\begin{bmatrix} lhs.x \\ lhs.y \\ lhs.z \\ lhs.w \end{bmatrix} == \begin{bmatrix} rhs.x \\ rhs.y \\ rhs.z \\ rhs.w \end{bmatrix} =\)
\((lhs.x == rhs.x) and (lhs.y == rhs.y) and (lhs.z == rhs.z) and (lhs.w == rhs.w)\)
Example
#include "include/vec4.h"
#include <iostream>
int main() {
nml::vec4 a(1.0f, 2.0f, 3.0f, 4.0f);
nml::vec4 b = a;
bool c = (a == b);
std::cout << c << std::endl;
return 0;
}
Result:
1
