vecpp :: Vec<typename, size_t>

vecpp::operator*,/(vecpp::Vec, T)

1)

template<typename T, std::size_t L>
constexpr Vec<T,L> operator*(const Vec<T,L>& vec, const T& scale);

template<typename T, std::size_t L>
constexpr Vec<T,L> operator*(const T& scale, const Vec<T,L>& vec);

2)

template<typename T, std::size_t L>
constexpr Vec<T,L> operator/(Vec<T,L>& vec, const T& scale);

Computes a vector representing the passed vector scaled by the operand.

1) Multiplies each member of the vector by the operand 2) Divides each member of the vector by the operand

Parameters

Argument	Role
vec	The vector to scale
scale	The scaling operand

Return value

A vector equivalent to vec with each of its members scaled by scale

N.B.

The implementation of the library may choose to use operator*(T, T) or operator*=(T&, T) interchangeably in order to implement this. If these two implementations are not consistent, then the result is undefined.

Example

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

int main() {
  using fVec2 = vecpp::Vec<float, 2>;

  fVec2 a = {10.0f, 5.0f};
  fVec2 b = a * 3.0f;

  assert(b[0] == 3.0f * 10.0f);
  assert(b[1] == 3.0f * 5.0f);
}
