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 Code int 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;
