Subject: Add basic tests for octal and hex notation in arithmetic expansions
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=09bb800c703a6a5683fda0d36c76e46a08e1d4d0;p=openbsd

Add basic tests for octal and hex notation in arithmetic expansions

POSIX requires only decimal, octal and hex, tests for the $((x#number))
notation could be useful too.
