使用bash将Hex转换为带符号的64位

Question

在bash中,需要将E83E67529A1090E7转换为-1711817203884453657

以下不起作用:

$ printf "%d\n" "0xE83E67529A1090E7"
-bash: printf: warning: 0xE83E67529A1090E7: Numerical result out of range
9223372036854775807

无符号和正符号值有效

$ printf "%d\n" "0x183E67529A1090E7"
1746947309936087271
$ printf "%u\n" "0xE83E67529A1090E7"
16734926869825097959

但我特别需要一个失败的负面签名值.

使用bashbase内置:

$ echo "$((16#E83E67529A1090E7))"
-1711817203884453657
