Greg offered several good suggestions to force base 10 in certain
situations.

No. Bash treats integer constants identically regardless of the context: a
leading 0 denotes octal. ksh93 treats constants with leading zeros
differently in different contexts (assigning to a variable with the integer
attribute set happens to be one of the cases where ksh93 treats a constant
as strictly decimal).
