numeric_limits::is_bounded

測試，如果型別可以表示的一組值會受到限制。

static const bool is_bounded = false;

傳回值

true ，如果型別有幾組可顯示的值， false ，否則為。

備註

所有預先定義的型別有幾組可顯示的值並傳回 true。

範例

// numeric_limits_is_bounded.cpp
// compile with: /EHsc
#include <iostream>
#include <limits>

using namespace std;

int main( )
{
   cout << "Whether float objects have bounded set "
        << "of representable values: "
        << numeric_limits<float>::is_bounded
        << endl;
   cout << "Whether double objects have bounded set "
        << "of representable values: "
        << numeric_limits<double>::is_bounded
        << endl;
   cout << "Whether long int objects have bounded set "
        << "of representable values: "
        << numeric_limits<long int>::is_bounded
        << endl;
   cout << "Whether unsigned char objects have bounded set "
        << "of representable values: "
        << numeric_limits<unsigned char>::is_bounded
        << endl;
}
