lo

auto eve::lo = functor<lo_t>

inlineconstexpr

Header file

#include <eve/module/core.hpp>

Callable Signatures

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

Parameters

• x : argument.

Return value

• Computes the elementwise lower significant half of the value bits, returning each element as an unsigned integer of half the size of the input element.

Note

If you also need the lower part hilo is more efficient.
