ljpart

kyosu::ljpart = {}

inlineconstexpr

Extracts the lj (seventh) part of a value.

Defined in Header

#include <kyosu/functions.hpp>

Callable Signatures

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

Parameters

• z: Original value.

Return value

Returns the seventh 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>

  std::cout << "Complex:     ";
  auto z = kyosu::complex_t<float>(3.5f,-2.9f);
