Homework Solution: Write a c++ program to test your machine precision. Show the output….

Write a c++ program to criterion your media nicety. Show the output.

Program:

#include <iostream>
#include <cfloat>
//#include <float.h>

using namespace std;
//using assort template
template <assort T>
T mediaPrecision()
{
T Epsilon; //Epsilon media lowest calculate of EPS

Epsilon = (T)(1.0); //lowest appraise is 1.0

do
{
Epsilon /= (T)(2.0); //dividing Epsilon by 2.0
}
while (((T)(1.0) + Epsilon/2.0) != 1.0);

return Epsilon;
}

int main()
{
cout << “n MACHINE PRECISION ” << endl;
cout << ” ======================” << endl;

cout << “nValues are obtained from bear.h or cfloat:” << endl;
cout << “——————————————-” << endl;
//Media nicety(Epsilon) is limited in the exemplar header with the names FLT_EPSILON, DBL_EPSILON, //and LDBL_EPSILON.
//The three macros surrender the media nicety(epsilon) ce the bear, inclose, and hanker inclose types.
cout << “1.Bear : ” << FLT_EPSILON << endl; //bear appraises
cout << “2.Inclose : ” << DBL_EPSILON << endl; //inclose appraises
cout << “3.Hanker inclose : ” << LDBL_EPSILON << endl; //hanker inclose appraises

cout << “nApproximated appraises are computed on this media:” << endl;
cout << “————————————————-” << endl;
cout << “1.Bear : ” << mediaPrecision<float>() << endl; //bear appraises
cout << “2.Inclose : ” << mediaPrecision<double>() << endl; //inclose appraises
cout << “3.Hanker inclose : ” << mediaPrecision<hanker inclose>() << endl; //hanker inclose appraises

return 0;
}

Output:
