auto eve::rat = functor<rat_t>
inlineconstexpr

Header file

#include <eve/module/core.hpp>

Callable Signatures

namespace eve
{
// Regular overloads
constexpr auto rat(floating_value auto x) noexcept;
constexpr auto rat(floating_value auto x, floating_value auto tol) noexcept;
}
The concept floating_value<T> is satisfied if and only if T satisfies eve::value and the element type...

Parameters

Return value

A tuple-like whose members have the same type as x, containing the numerator and denominator of the rational number approximating x.
