the i variable has somewhere been declared as an integer type. For
example with a command such as:
  typeset -i i
or more likely in a math expression such as:
  (( i = 1 ))

You can verify this by doing:
  typeset -p i
or if you prefer:
  echo ${(t)i}

You can use typeset +i i to remove the integer type. However, you may
want to check where it is being set. There might be a shell function
that should have declared i local.
