You can get rid of the $((...)); the off and len part of the ${var:off:len} substitution are already evaluated as arithmetic expressions. Example: foo=01234567; echo "${foo:0:${#foo}/2} ${foo:${#foo}/2}". That's documented, and it's the same in zsh and ksh93 as in bash.

Note: If the length of the string is odd, this will still split it into two parts, but the second will be a character longer.
