Compile-time rational arithmetic. More...

Classes
struct	ratio< Num, Denom >
	The typename template provides compile-time rational arithmetic support. Each instantiation of this template exactly represents any finite rational number as long as its numerator Num and denominator Denom are representable as compile-time constants of type intmax_t. More...

struct	ratio_equal< R1, R2 >
	Compares two ratio objects for equality at compile-time. If the ratios R1 and R2 are equal, provides the member constant value equal true. Otherwise, value is false. More...

struct	ratio_greater< R1, R2 >
	Compares two ratio objects for equality at compile-time. If the ratio R1 is greater than the ratio R2, provides the member constant value equal true. Otherwise, value is false. More...

struct	ratio_greater_equal< R1, R2 >
	Compares two ratio objects for equality at compile-time. If the ratio R1 is greater than or equal to the ratio R2, provides the member constant value equal true. Otherwise, value is false. More...

struct	ratio_less< R1, R2 >
	Compares two ratio objects for equality at compile-time. If the ratio R1 is less than the ratio R2, provides the member constant value equal true. Otherwise, value is false. More...

struct	ratio_less_equal< R1, R2 >
	Compares two ratio objects for equality at compile-time. If the ratio R1 is less than or equal to the ratio R2, provides the member constant value equal true. Otherwise, value is false. More...

struct	ratio_not_equal< R1, R2 >
	Compares two ratio objects for equality at compile-time. If the ratios R1 and R2 are not equal, provides the member constant value equal true. Otherwise, value is false. More...

Typedefs
template<typename R1, typename R2>
using	ratio_add = ratio<R1::num * R2::den + R2::num * R1::den, R1::den * R2::den>
	The alias template ratio_add denotes the result of adding two exact rational fractions represented by the ratio specializations R1 and R2.

template<typename R1, typename R2>
using	ratio_divide = ratio<R1::num * R2::den, R1::den * R2::num>
	The alias template ratio_divide denotes the result of dividing two exact rational fractions represented by the ratio specializations R1 and R2.

template<typename R1, typename R2>
using	ratio_multiply = ratio<R1::num * R2::num, R1::den * R2::den>
	The alias template ratio_multiply denotes the result of multiplying two exact rational fractions represented by the ratio specializations R1 and R2.

template<typename R1, typename R2>
using	ratio_subtract = ratio<R1::num * R2::den - R2::num * R1::den, R1::den * R2::den>
	The alias template ratio_subtract denotes the result of subtracting two exact rational fractions represented by the ratio specializations R1 and R2.
