The difference is returned to level 1, just as for other numbers.
You can mix binary integers and real numbers in your calculations. A
normal real integer (entered without the # delimiter) is interpreted in
base 10 regardless of the current binary integer base.
For example, calculate
the address 2710 less than the given address.
