Fraction problem

[HaoZ]

Hi rooter,

I got a simple question. When I tried to calculate a fraction say 33/99 by root. I cout <<33/99<<endl; but I got 0 instead of 0.33333. How could I obtain decimals instead but not an integer as result?

Since both are integers, the operation is called for integers. For float or double operation, at least one of the numbers should be a float or double; e.g.

1.0 * 33 / 99
33.0 / 39
(double)(33)/99

etc. but not (double)(33/99), since the integer 33/99 would be done first, giving zero.

Thanks so much!
