conversion from double to unsigned int

Question

I am facing a problem with the conversion of value from Double to int. I try to run the following code :

int main()
{
    double val_d= 6.25e-05;
    cout &l         


        

Answer 1

difference in rounding.

1. (1/val_d) - double is rounded to the nearest possible number that can be represented with double precision; (ex.: 3.6999999999999999 == 3.7)
2. (unsigned int ) (1/val_d) - when casting to int decimal part is truncated, that results on rounding down (ex.: int(3.6) == 3
