float32

eve::float32 = {}

inlineconstexpr

convert a eve::value to a float32 based eve::floating_value.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value T >
   as_wide_as<T, float> float32(T x) noexcept; //1
 
   template< eve::callable C >
   as_wide_as<T, float> float32(C x) noexcept; //2
}

Parameters

• x : argument.

Return value

• if x is an eve::simd_value, returns a value, of type wide <float, cardinal_t<T>>,
• if x is an eve::scalar_value, returns a value of type float,
• if x is a supported callable a call to float32(x)(...) is semantically equivalent to float32(x(...)).

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_64t = eve::wide<std::uint64_t, eve::fixed<4>>;
using wide_8t = eve::wide<std::uint8_t, eve::fixed<4>>;
 
int main()
{
  wide_64t p64 = {1, 2, 100, eve::valmax(eve::as<std::int64_t>())};
 
  std::cout << "---- simd" << '\n'
            << "<- p64                      = " << p64 << '\n'
            << "-> float32(p64)             = " << eve::float32(p64) << '\n';
  return 0;
