Description

Getting the Minimum and Maximum Values for a Numeric Type, such as an int or double.

Demo Code

#include <iostream>
#include <limits>

using namespace std;

template<typename T>
void showMinMax() {
   cout << "min: " << numeric_limits<T>::min() << endl;
   cout << "max: " << numeric_limits<T>::max() << endl;
   cout << endl;/*from  w  w  w.ja  v a2 s  .  c o m*/
}

int main() {

   cout << "short:" << endl;
   showMinMax<short>();
   cout << "int:" << endl;
   showMinMax<int>();
   cout << "long:" << endl;
   showMinMax<long>();
   cout << "float:" << endl;
   showMinMax<float>();
   cout << "double:" << endl;
   showMinMax<double>();
   cout << "long double:" << endl;
   showMinMax<long double>();
   cout << "unsigned short:" << endl;
   showMinMax<unsigned short>();
   cout << "unsigned int:" << endl;
   showMinMax<unsigned int>();
   cout << "unsigned long:" << endl;
   showMinMax<unsigned long>();
}
