vecpp :: reference :: Angle<typename>

vecpp::operator+=,-=(vecpp::Angle)

template<typename T>
constexpr Angle<T>& operator+=(Angle<T>& lhs, const Angle<T>& rhs);

template<typename T>
constexpr Angle<T>& operator-=(Angle<T>& lhs, const Angle<T>& rhs);

Numerically combine two angles, storing the result into the first.

Parameters

Argument	Role
lhs	The left-hand side of the operation and the destination
rhs	The right-hand side of the operation

Return value

A reference to lhs

Example

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

int main() {
  using Angle = vecpp::Angle<float>;

  auto angle_a = Angle::from_deg(90.0f);
  auto angle_b = Angle::from_deg(180.0f);

  angle_a += angle_b;

  std::cout << angle_a << "\n";
}

Output:

-90°
