Is there a trunc function in C++?

Question

I searched around and couldn\'t find the trunc function for C++. I know I can do this:

int main()
{
    double a = 12.566789;
    cout <<          


        

Answer 1

trunc is there, in :

#include 
#include 

int main() {
        std::cout << trunc(3.141516) << std::endl; 
}

I suppose you're looking for something else?
