minlogdenormal

auto eve::minlogdenormal = functor<minlogdenormal_t>

inlineconstexpr

Defined in Header

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
   template< eve::floating_value T >
   T minlogdenormal(as<T> x) noexcept;
}

Parameters

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

Return value

The call eve::minlogdenormal(as<T>()) returns the least value for which eve::exp is not zero.

Example

#include <eve/module/math.hpp>
#include <eve/wide.hpp>
#include <iostream>
#include <iomanip>
 
using wide_ft = eve::wide<float>;
 
template<typename T>
consteval auto constexpr_minlogdenormal() { return eve::minlogdenormal(eve::as<T>{}); }
 
int main()
