ios::binary isn't your problem, it is the 'put to' operator <<. Think of
it
as sort of a hardwired fprintf. the << for any built-in type has one
mission in
life: turning that data into a formatted textual representation. see
Stroustrup's 3rd,
21.2.2

 try the 'write' ostream class member. don't
let the 'char' in the prototype throw you, you just need to pass
&someval and sizeof(someval)  to write ints, doubles, structures, or
what have you.
