minf

eve::minf = {}

inlineconstexpr

Computes the -infinity ieee value.

Callable object computing the negative infinity value.

Defined in Header

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
   template< eve::value T >
   T minf(as<T> x) noexcept;
}

Parameters

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

Return value

The call eve::minf(as<T>()) is semantically equivalent to T(-std::numeric_limits<eve::element_type_t<T>>::infinity())

Example

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

operator()	Computes the minf constant

---

template < floating_value T > T operator()( as<T> const & t) const noexcept;

Parameters

t: Type wrapper instance embedding the type of the constant.

Return value

the call eve::minf(as<T>()) is semantically equivalent to T(-std::numeric_limits<t_t>::infinity())
