• Masked Call

  The call eve;is_gtz[mask](x) provides a masked version of eve::is_gtz which is equivalent to if_else (mask, is_gtz(x), eve::false( eve::as(x))).

  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, -0.0f};
   
    std::cout << "---- simd" << '\n'
              << "<- pf         = " << pf << '\n'
              << "-> is_gtz[pf > 0](pf) = " << eve::is_gtz[pf > 0](pf) << '\n';
    return 0;
