Hi all,

assuming this code:

1 2 3 4 5 6


int a;

a = 90 / 20;

cout << "a"<<a<<endl; // output is 4

How can i declare the variable if i want :

1- to get 90 /20 = 4.5

2- to get 90/20 = 5

thanks for each advance

You can declare it as `double a;` for it to be able to take decimal points. You can round up / round down a value using <cmath>'s two functions - * ceil - http://www.cplusplus.com/reference/clibrary/cmath/ceil/ (rounding up) * floor - http://www.cplusplus.com/reference/clibrary/cmath/floor/ (rounding down)

Also, you need to change either 90 or 20 to a float/double (otherwise you will get 4 because of integer division).
