invlog10_2

auto eve::invlog10_2 = functor<invlog10_2_t>

inlineconstexpr

Defined in Header

#include <eve/module/math.hpp>

Callable Signatures

namespace eve
{
   template< eve::floating_value T >
   T invlog10_2(as<T> x) noexcept;
}

Parameters

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

Return value

The call eve::invlog10_2(as<T>()) returns the inverse of \(\log_{10}2\).

Example

#include <eve/module/math.hpp>
#include <eve/wide.hpp>
#include <iostream>
#include <iomanip>
 
using wide_ft = eve::wide<float>;
