Bash Version: 3.2 Patch Level: 13 Release Status: release
Description: $ echo $((4000000000*4000000000) -2446744073709551616 Repeat-By: Do some arithmetic in bash $((....)). If the numbers are out of range, the output will be wrong in all sorts of interesting ways. No error message is given. Fix: Arbitrary-precision maths would be nice. But at least, could we have an error message if an overflow occurs? The man page says: "Evaluation is done in fixed-width integers with no check for overflow..." but I'd suggest this represents a bug, not a feature.
