You really ought be only using POSIX defined sh operators,
from two more POSIX compatible shells (in this regard...):

jinx$ sh -c 'printf '%6s' "$((10#$i))"'
sh: arithmetic: unexpected '#' (0x23) in expression
jinx$ fbsh !*
fbsh -c 'printf '%6s' "$((10#$i))"'
fbsh: arithmetic expression: expecting EOF: "10#"

Leading "base#" is not part of the sh language at all, and so
should not be expected to work at all, let alone in any particular way.
