This is why % and // seem out of place to me; integers are not a

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?)
