maxexponentp1

eve::maxexponentp1 = functor<maxexponentp1_t>

inlineconstexpr

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
  template<eve::floating_value T> constexpr eve::as_integer<T> maxexponentp1(as<T> x);
}

Parameters

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

Return value

the call eve::maxexponentp1(as<T>()) is semantically equivalent to

• as_integer_t<T>(128) if eve::element_type_t<T> is float
• as_integer_t<T>(1024) 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_maxexponentp1() { return eve::maxexponentp1(eve::as<T>{}); }
 
int main()
{
  wide_ft wxf;
 
  std::cout << "---- simd"  << std::endl
            << "-> maxexponentp1(as<wide_ft>())  = " << eve::maxexponentp1(eve::as<wide_ft>()) << std::endl
            << "-> maxexponentp1(as(wxf))        = " << eve::maxexponentp1(eve::as(wxf))       << std::endl;
 
  double       xf;
 
  std::cout << "---- scalar" << std::endl
            << "-> maxexponentp1(as<float>())    = " << eve::maxexponentp1(eve::as(float())) << std::endl
            << "-> maxexponentp1(as<xf))         = " << eve::maxexponentp1(eve::as(xf)) << std::endl;
 
  std::cout << "-> constexpr maxexponentp1            = " << constexpr_maxexponentp1<float>() << std::endl;
 
  return 0;
