Operating Systems OS X (Apple) Unsigned to signed, error?... Post 302904983 by Don Cragun on Sunday 8th of June 2014 11:13:42 PM

The printf utility (like the C printf()), never truncates integral numeric values. You can however use a logical and operation to truncate the value:
Code:
printf "%04X\n" $((num & 0xFFFF))
