Generating Random Float Values

To generate random floating numbers, choose a floating point number, divide it by the largest value of int type and multiply the result by the value of a function that generates random integers, say rand():
#include <limits> // for std::numeric_limits
#include <cstdlib> // for rand and srand
#include <ctime> // for time()
using namespace std;
int main()
 srand(time(0)); // random seed
 float rand_val=
  100000.0/numeric_limits<unsigned int>::max() * rand();
