C++ - minimum and maximum double value
7 points
In this short article, we would like to show how to get in C++ minimal and maximal double value.
Quick solution:
xxxxxxxxxx1
// #include <limits>2
3
double min = std::numeric_limits<double>::min(); // minimum positive value4
double max = std::numeric_limits<double>::max(); // maximum positive value5
double lowest = std::numeric_limits<double>::lowest(); // minimum negative value
In the below example we use numeric_limits API that provides current max and min values.

4
using namespace std;5
6
int main()7
{8
double min = numeric_limits<double>::min(); // minimum positive value9
double max = numeric_limits<double>::max(); // maximum positive value10
double lowest = std::numeric_limits<double>::lowest(); // minimum negative value11
12
cout << "min: " << min << endl; // min: 2.22507e-30813
cout << "max: " << max << endl; // max: 1.79769e+30814
cout << "lowest: " << lowest << endl; // lowest: -1.79769e+30815
16
return 0;17
}Output:
xxxxxxxxxx1
min: 2.22507e-3082
max: 1.79769e+3083
lowest: -1.79769e+308
