Re: How to get a double from the quotient of two int values?

If you explicitly cast either operand to a double you'll get the double
division operator and the other operand will be implicitly cast.

So:
x = (double) a / b;
or:
x = a / (double) b;

should do it but maybe the following shows exactly what you're doing?

x = (double) a / (double) b;

Obviously:

double a = 3;

would do the job too. It really depends what you're trying to achieve.
