It is sometimes useful to do integer arithemetic; a useful subset of Lua numbers are integers. A number of interesting algorithms involve integer arithmetic.
But as you say, % (and //) are welldefined for nonintegers, and they do have uses even if they haven't been useful for you. (I have $1.38 in my pocket, and apples cost $0.16 each. How many apples can I buy?)
