C++中的RealOpGuangeRealSub()函数

这个 比率(大于等于) 是C++中的一个内置函数,它检查比率R1是否大于或等于R2。如果比率大于或等于比率2,则返回True,否则返回false。

null

语法:

template < class ratio1_name, class ratio2_name > ratio_greater_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大于或等于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:

// C++ program to illustrate the
// ratio_greater_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_greater_equal<ratio1, ratio2>::value)
cout << "3/9 is greater than or equal to 1/3" ;
else
cout << "3/9 is less than 1/3" ;
return 0;
}


输出:

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

项目2:

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


输出:

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

方案3:

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


输出:

1/10 is less than 1/8
