Useless use of -i is usually unhelpful. In Bash (but not all shells), it's slower, because it's still just storing the value as a string and marking the variable with the integer attribute which modifies the way certain assignments behave. It doesn't do any harm in this specific case, but there are a lot of gotchas with -i to be aware of if you're going to use it. -- Dan Douglas
