logical_not

eve::logical_not = functor<logical_not_t>

inlineconstexpr

Header file

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   constexpr auto logical_not(auto logical_value x) noexcept;
}

Parameters

• x: argument.

Return value

The call logical_not(x) is semantically equivalent to is_eqz(x). Infix notation can be used with !x.

Note

Although the infix notation with ! is supported, the ! operator on standard scalar types is the original one and so will return bool instead of eve::logical_value.

Example

// revision 0
#include <eve/module/core.hpp>
#include <iostream>
 
int main()
{
  eve::wide wu0{0u, 1u, 2u, 3u, 4u, 5u, 6u, 7u};
 
  std::cout << "<- wu0                                = " << wu0 << "\n";
                                                      
  std::cout << "-> logical_not(wu0 <= maximum(wu0)/2) = " << eve::logical_not(wu0 <= eve::maximum(wu0)/2) << "\n";
