broadcast

eve::broadcast = {}

inlineconstexpr

Computes the.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value T >
   T broadcast(T x) noexcept;
}

Parameters

• x: An instance of an SIMD value
• i: An eve::index indicating which lane of x to broadcast

Return value

• If x is an instance of an SIMD value T, the call is equivalent to T{x.get(I)}.
• If x is an instance of a scalar value the call simply returns x

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_ft = eve::wide<float, eve::fixed<4>>;
using wide_it = eve::wide<std::int16_t, eve::fixed<8>>;
 
int main()
{
  wide_ft pf = {1.2f,0.34f,0.056f,0.0078f};
  wide_it pi = {-1, 2,-3, 4,-5, 6,-7, 8};
 
  std::cout << pf << "\n"
            << eve::broadcast(pf, eve::index<3> ) << "\n";
 
  std::cout << "\n";
 
  std::cout << pi << "\n"
            << eve::broadcast(pi, eve::index<5> ) << "\n";
