C++ floating point to integer type conversions

Question

What are the different techniques used to convert float type of data to integer in C++?

#include 

using namespace std;
struct database {
  i         


        

Answer 1

Check out the boost NumericConversion library. It will allow to explicitly control how you want to deal with issues like overflow handling and truncation.

Answer 2

Normal way is to:

float f = 3.4;
int n = static_cast<int>(f);
