mindenormal

eve::mindenormal = functor<mindenormal_t>

inlineconstexpr

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
  template<eve::plain_value T> constexpr T mindenormal(as<T> x) noexcept;
}

Parameters

• x : Type wrapper instance embedding the type of the constant.

Return value

The call eve::mindenormal(as<T>()) is semantically equivalent to:

• ‘T(1)’ if eve::element_type_t<T> is integral
• T(1.4013e-45f) if eve::element_type_t<T> is float
• T(4.94066e-324) if eve::element_type_t<T> is double

Example

#include <eve/module/core.hpp>
#include <eve/wide.hpp>
#include <iostream>
 
using wide_ft = eve::wide<float>;
 
template<typename T>
consteval auto constexpr_mindenormal() { return eve::mindenormal(eve::as<T>{}); }
 
int main()
{
  wide_ft wxf;
 
  std::cout << "---- simd"  << std::endl
            << "-> mindenormal(as<wide_ft>())  = " << eve::mindenormal(eve::as<wide_ft>()) << std::endl
            << "-> mindenormal(as(wxf))        = " << eve::mindenormal(eve::as(wxf))       << std::endl;
 
  double       xf;
 
  std::cout << "---- scalar" << std::endl
            << "-> mindenormal(as<float>())         = " << eve::mindenormal(eve::as(float())) << std::endl
            << "-> mindenormal(as<xf))              = " << eve::mindenormal(eve::as(xf)) << std::endl;
 
  std::cout << "-> constexpr mindenormal            = " << constexpr_mindenormal<float>() << std::endl;
 
  return 0;
