floating_

eve::floating_ = {}

inlineconstexpr

convert a eve::value to an eve::floating_value.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

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

Parameters

• x : argument.

Return value

• if x is an eve::simd_value, returns a value, of typewide <i_t, cardinal_t<T>>,
• if x is an eve::scalar_value, returns a value of type i_t,
• if x is a supported callable a call to floating_(x)(...) is semantically equivalent to floating_(x(...)).

where i_t is eve::as_floating_point_t<eve::element_type_t<T>>

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_8t = eve::wide<std::int8_t, eve::fixed<4>>;
using wide_64t = eve::wide<std::uint64_t, eve::fixed<4>>;
 
int main()
{
  wide_8t p8 = {-1, -3, 6, 127};
  wide_64t p64 = {1, 2, 100, eve::valmax(eve::as<std::int64_t>())};
 
  std::cout << "---- simd" << '\n'
            << "<- p8                         = " << p8 << '\n'
            << "-> floating_(p8)              = " << eve::floating_(p8) << '\n'
            << "<- p64                        = " << p64 << '\n'
            << "-> floating_(p64)             = " << eve::floating_(p64) << '\n';
  return 0;
