std::numeric_limits<T>::denorm_min() in C++ with Example
The std::numeric_limits<T>::denorm_min() function in C++ STL is present in the <limits> header file. This function is used to find the smallest non-zero denormalized value.
Header File:
#include<limits>
Template Class:
static T denorm_min() throw(); static constexpr T denorm_min() noexcept;
Syntax:
std::numeric_limits<T>::denorm_min()
Parameter: The function std::numeric_limits<T>::denorm_min() does not accept any parameter.
Return Value: The functionstd::numeric_limits<T>::denorm_min() returns the smallest nonzero denormalized value of data type T.
Below is the program to demonstrate std::numeric_limits<T>::denorm_min() in C++:
Program:
// C++ program to illustrate// std::numeric_limits<T>::denorm_min()#include <bits/stdc++.h>#include <limits>using namespace std; // Driver Codeint main(){ // Print the denormalised value for // different data types cout << "For float: " << numeric_limits<float>::denorm_min() << endl; cout << "For int: " << numeric_limits<int>::denorm_min() << endl; cout << "For double: " << numeric_limits<double>::denorm_min() << endl; cout << "For long int: " << numeric_limits<long int>::denorm_min() << endl; cout << "For long double: " << numeric_limits<long double>::denorm_min() << endl; return 0;} |
Output:
For float: 1.4013e-45 For int: 0 For double: 4.94066e-324 For long int: 0 For long double: 3.6452e-4951
