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 well-defined for 
non-integers, 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?)
