C++中的RealOffLySyQualAuto()函数

这个 比率_减去_等于() 是C++中的一个内置函数,它检查比率R1是否小于或等于R2。如果比率小于或等于比率2,则返回True,否则返回false。 语法:

null
template < class ratio1_name, class ratio2_name > ratio_less_equal

模板参数 该函数接受两个模板参数 比率1 比率2 这些都是可以比较的。 返回值: 如果ratio1小于或等于ratio2,则函数返回布尔值,否则返回false。 以下程序说明了上述功能: 项目1:

CPP

// C++ program to illustrate the
// ratio_less_equal function
// when both the ratios are equal
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
typedef ratio<3, 9> ratio1;
typedef ratio<1, 3> ratio2;
// check if R1<=R2
if (ratio_less_equal<ratio1, ratio2>::value)
cout << "3/9 is less than or equal to 1/3" ;
else
cout << "3/9 is greater than 1/3" ;
return 0;
}


输出:

3/9 is less than or equal to 1/3

项目2:

CPP

// C++ program to illustrate the
// ratio_less_equal function
// to show less than
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
typedef ratio<1, 3> ratio1;
typedef ratio<1, 2> ratio2;
// check if R1<=R2
if (ratio_less_equal<ratio1, ratio2>::value)
cout << "1/3 is less than or equal to 1/2" ;
else
cout << "1/3 is greater than 1/2" ;
return 0;
}


输出:

1/3 is less than or equal to 1/2

方案3:

CPP

// C++ program to illustrate the
// ratio_less_equal function
// to show when greater than
#include <iostream>
#include <ratio>
using namespace std;
int main()
{
typedef ratio<1, 8> ratio1;
typedef ratio<1, 10> ratio2;
// check if R1<=R2
if (ratio_less_equal<ratio1, ratio2>::value)
cout << "1/8 is less than or equal to 1/10" ;
else
cout << "1/8 is greater than 1/10" ;
return 0;
}


输出:

1/8 is greater than 1/10
