commit af9d7fb6d21010469032446616721dfa75a942ab diff: https://github.com/bitrig/bitrig/commit/af9d7fb author: Martin Natano <[email protected]> date: Wed Mar 4 20:46:43 2015 +0100 Let expr(1) perform long arithmetic (not plain int). Thats also what $(()) in ksh does. Doing something else in expr seems stupid. At least, it is unexpected. found by pedro@ M bin/expr/expr.c
