With
Here is an example
#include
#include
int main()
{
double d = 122.345;
std::cout << std::fixed;
std::cout << std::setprecision(2);
std::cout << d;
}
And you will get output
122.34
You were nearly there, need to use std::fixed as well, refer http://www.cplusplus.com/reference/iostream/manipulators/fixed/
#include
#include
int main(int argc, char** argv)
{
float testme[] = { 0.12345, 1.2345, 12.345, 123.45, 1234.5, 12345 };
std::cout << std::setprecision(2) << std::fixed; for(int i = 0; i < 6; ++i) { std::cout << testme[i] << std::endl; } return 0; } outputs: 0.12 1.23 12.35 123.45 1234.50 12345.00
