two_add

auto eve::two_add = functor<two_add_t>

inlineconstexpr

Header file

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   constexpr auto two_add(floating_value auto x, floating_value auto y) noexcept;
}

Parameters

• x, y: floating arguments.

Return value

Computes elementwise a pair of values [a,e] such that:

• a is x+y
• e is a value such that a \(\oplus\)e is equal to x \(\oplus\)y, where \(\oplus\) adds its two parameters with infinite precision.

Example

// revision 1
#include <eve/module/core.hpp>
#include <iostream>
 
int main()
{
  eve::wide wf0 = {3.0, 2.5, -32.7, 1.0};
  eve::wide wf1 = {4.2, 1.5, -100.834, eve::eps(eve::as<double>())/2};
 
  std::cout << "<- wf0               = " << wf0 << "\n";
  std::cout << "<- wf1               = " << wf1 << "\n";
 
  std::cout << "-> two_add(wf0, wf1) = " << eve::two_add(wf0, wf1) << "\n";
