binarize_not

eve::binarize_not = {}

inlineconstexpr

transform logical values to numerical values

binarize_not(c, v) is semantically equivalent to: if_else(c, T(0), v);

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value C  >
   C binarize_not(eve::as_logical<C> c) noexcept;          //1
 
   template<eve::value C, eve::value V >
   T binarize_not(eve::as_logical<C> c, T v) noexcept;     //2
}

Parameters

• c : condition.
• v : value to return if the condition is not met (C(1) if omitted).

Return value

1. The value of if_else(c, T(0), v) is returned.
2. The value of if_else(c, C(0), C(1)) is returned.

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_ft = eve::wide <float, eve::fixed<4>>;
 
int main()
{
  wide_ft pf = { 0.0f, 1.0f, -1.0f, -0.5f};
