eve::lohi = functor<lohi_t>

inlineconstexpr

Header file

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   constexpr auto lohi(value auto x) noexcept;
}

Parameters

• x : argument.

Return value

• Computes the elementwise the lower and higher parts of the input values, as a pair of unsigned integers of half size
• The call [l, h] = lohi(x) is_semantically equivalent to l = lo(x); h = hi(x);
