maxflint

auto eve::maxflint = functor<maxflint_t>

inlineconstexpr

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

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

Parameters

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

Return value

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

• T(2048.0f) if eve::element_type_t<T> is float16.
• T(16777216.0f) if eve::element_type_t<T> is float.
• T(9007199254740992.0) if eve::element_type_t<T> is double.

Example

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