vecpp :: Vec<typename, size_t>

vecpp::norm(vecpp::Vec)

template<typename T, std::size_t L>
constexpr T norm(const Vec<T,L>& arg);

Returns the euclidian norm of the vector

Parameters

Argument	Role
arg	The vector we want the legnth of

Return value

The norm of the vector.

Example

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

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

  fVec2 a = {3.0f, 0.0f};
  fVec2 b = {1.0f, 1.0f};

  assert(norm(a) == 3.0f);
  assert(norm(b) == std::sqrt(2.0f));
}
