[edit]

Defined in header`<ratio>`
template<class R1,class R2> struct ratio_not_equal:std::integral_constant<bool,/* see below */>{};		(since C++11)

If the ratiosR1 andR2 are not equal, provides the member constantvalue equaltrue. Otherwise,value isfalse.

[edit]Helper variable template

template<class R1,class R2> constexprbool ratio_not_equal_v= ratio_not_equal<R1, R2>::value;		(since C++17)

Member constants

value

[static]

true ifR1::num!= R2::num|| R1::den!= R2::den,false otherwise
(public static member constant)

Member functions

operator bool	converts the object tobool, returnsvalue (public member function)
operator() (C++14)	returnsvalue (public member function)

Member types

Type	Definition
`value_type`	bool
`type`	std::integral_constant<bool, value>

[edit]Possible implementation

template<class R1,class R2>struct ratio_not_equal:std::integral_constant<bool,!std::ratio_equal<R1, R2>>{};

[edit]Example

Run this code

#include <ratio> static_assert(std::ratio_not_equal_v<std::ratio<6,9>,std::ratio<9,6>>,"6/9 != 9/6"); int main(){}
