[Vala] Int64 operations, I'm confused

[raum no-log org]

There is something I do not understand. I try to make a simple operation
and here is the result.
(...)
                int64 val1 = 96;
                int64 val2 = val1 / 8;
                stdout.printf ("val1: %lld, val2 : %d\n", val1, val2);

                int val4 = 96;
                int val5 = val4 / 8;
                stdout.printf ("val4: %lld, val5 : %d\n", val4, val5);

(..)

Results :
val1: 96, val2 : 0
val4: 96, val5 : 12

In fact I want to use file.query_info() which returns an int64 for size
(actually 96 bytes). And I need to divide size by 8.... result => 0

Any advice ? :)

Thanks
