bitincrement

auto eve::bitincrement = functor<bitincrement_t>

inlineconstexpr

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
  template< eve::plain_value T > constexpr T bitincrement(as<T> x) noexcept;
}

Parameters

• x : Type wrapper instance embedding the type of the constant.

Return value

The call eve::bitincrement(as<T>()) returns a value of type T with only the least significant bit set.

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_ft = eve::wide<float>;
using wide_it = eve::wide<std::int16_t>;
 
template<typename T>
consteval auto constexpr_bitincrement() { return eve::bitincrement(eve::as<T>{}); }
 
int main()
