inject

auto kyosu::inject = eve::functor<inject_t>

inlineconstexpr

inject a real in the complex plane a nan producing a fnan.

Header file

#include <kyosu/functions.hpp>

Callable Signatures

namespace kyosu
{
  template<kyosu::concepts::cayley_dickson_like Z> constexpr complexify_t<Z> inject(Z z) noexcept;
}

Parameters

• z: Value to process.

Return value

• same as complex(z) for real typed z, except that real nan produces complex fnan if pedantic option is usedand acts as identity on other cayley_dickson_like
