Actually, you can use it to _count_ as long as all individual items are
integers. Double precision is built that way to keep integer arithmetics
clean as long as all operands are integers and results of all
intermediate operations are integers. So:

integer * integer = ok
integer + integer = ok
integer - integer = ok
integer / integer = could present problems

Since _counting_ is only addition, it is safe to do even with double.
