mundy::NumTraits< long double > Struct Reference

long double traits; nonzero fuzzy-comparison precision.

#include <NumTraits.hpp>

Inheritance diagram for mundy::NumTraits< long double >:

Public Types
using	Real
	The real-valued counterpart of T (T itself for real scalars).
using	NonInteger
	A type closed under division and roots; integers widen to double, others are unchanged.
using	Literal
	The type of a numeric literal paired with a value of type T.

Static Public Member Functions
static constexpr long double	dummy_precision ()
static constexpr Real	epsilon ()
	Machine epsilon: the gap between 1 and the next representable value.
static constexpr Real	dummy_precision ()
	Loose tolerance for fuzzy comparisons; 0 for exact types.
static constexpr Real	highest ()
	Largest finite representable value.
static constexpr Real	lowest ()
	Most negative finite representable value (min() for integers, -max() for floats).
static constexpr Real	norm_min ()
	Smallest positive normalized value.
static constexpr Real	infinity ()
	Positive infinity (or highest() for types without an infinity).
static constexpr Real	quiet_NaN ()
	A quiet NaN.

Static Public Attributes
static constexpr bool	IsInteger
	Whether T represents integers.
static constexpr bool	IsSigned
	Whether T is a signed type.
static constexpr bool	IsComplex
	Whether T is complex; always false (complex scalars are not supported).
static constexpr bool	RequireInitialization
	Whether T must be constructed before use (true for non-trivial custom scalars).
