lpart

kyosu::lpart = {}

inlineconstexpr

Extracts the l (fifth) part of a value.

Defined in Header

#include <kyosu/functions.hpp>

Callable Signatures

namespace kyosu
{
   template<kyosu::concepts::cayley_dickson T> constexpr auto& lpart(T& z)        noexcept;
   template<kyosu::concepts::cayley_dickson T> constexpr auto  lpart(T const& z)  noexcept;
   template<eve::floating_ordered_value T>     constexpr T     lpart(T const& z)  noexcept;
}

Parameters

• z: Original value.

Return value

Returns the fifth part of its argument.

For up to quaterion inputs, the call always returns 0.

Example

#include <kyosu/kyosu.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
int main()

  std::cout << "Real:        ";
  float f = 72.9f;
  std::cout << f << " -> " << lpart(f) << "\n";
 
  std::cout << "Complex:     ";
  auto z = kyosu::complex_t<float>(3.5f,-2.9f);
  std::cout << z << " -> " << lpart(z) << "\n";
 
  std::cout << "Quaternion:  ";
