n = string.atoi("0xFFFF",16)
n = n + 0xFFFF
print n

The optional second argument to string.atoi() is the base from which you
wish to convert.

Once strings are converted to integers, they're just computer numbers;
you only have to worry about the radix (base) when you want to read them
in or print them out.  By default, atoi() and print assume you want to
read and see them in decimal.
