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

Write a c++ program to trial your utensil nicety. Show the output.

Program:

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

using namespace std;
//using systematize template
template <systematize T>
T utensilPrecision()
{
T Epsilon; //Epsilon instrument meanest calculate of EPS

Epsilon = (T)(1.0); //meanest estimate 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;
//Utensil nicety(Epsilon) is fixed in the trutination header with the names FLT_EPSILON, DBL_EPSILON, //and LDBL_EPSILON.
//The three macros produce the utensil nicety(epsilon) for the bear, envelop, and hanker envelop types.
cout << “1.Bear : ” << FLT_EPSILON << endl; //bear estimates
cout << “2.Envelop : ” << DBL_EPSILON << endl; //envelop estimates
cout << “3.Hanker envelop : ” << LDBL_EPSILON << endl; //hanker envelop estimates

cout << “nApproximated estimates are computed on this utensil:” << endl;
cout << “————————————————-” << endl;
cout << “1.Bear : ” << utensilPrecision<float>() << endl; //bear estimates
cout << “2.Envelop : ” << utensilPrecision<double>() << endl; //envelop estimates
cout << “3.Hanker envelop : ” << utensilPrecision<hanker envelop>() << endl; //hanker envelop estimates

return 0;
}

Output:
