uint64

eve::uint64 = {}

inlineconstexpr

convert a eve::value to a std::uint64_t based eve::value.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value T >
   as_wide_as<T, std::uint64_t> uint64(T x) noexcept; //1
 
   template< eve::callable C >
   as_wide_as<T, std::uint64_t> uint64(C x) noexcept; //2
}

Parameters

• x : argument.

Return value

• if x is an eve::simd_value, returns a value, of typewide <std::uint64_t, cardinal_t<T>>,
• if x is an eve::scalar_value, returns a value of type std::uint64_t,
• if x is a supported callable a call to uint64(x)(...) is semantically equivalent to uint64(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::int64_t, eve::fixed<4>>;
 
int main()
{
  wide_ft pf = {-1.0f, 2.3f, 45000.7f, -10.6f};
  wide_it pi = {-1, 2, 100, eve::valmax(eve::as<std::int64_t>())};
 
  std::cout << "---- simd" << '\n'
            << "<- pf                     = " << pf << '\n'
            << "-> uint64(pf)             = " << eve::uint64(pf) << '\n'
            << "<- pi                     = " << pi << '\n'
            << "-> uint64(pi)             = " << eve::uint64(pi) << '\n';
  return 0;
