underflow_error Class

The class serves as the base class for all exceptions thrown to report an arithmetic underflow.

class underflow_error : public runtime_error {
public:
    explicit underflow_error(const string& message);
    explicit underflow_error(const char *message);
};

Remarks

The value returned by what is a copy of message.data.

Example

// underflow_error.cpp
// compile with: /EHsc /GR
#include <iostream>

using namespace std;

int main( )
{
   try 
   {
      throw underflow_error( "The number's a bit small, captain!" );
   }
   catch ( exception &e ) {
      cerr << "Caught: " << e.what( ) << endl;
      cerr << "Type: " << typeid( e ).name( ) << endl;
   };
}

Caught: The number's a bit small, captain!
