Which platform can we expect one's complement being used there?
- by Jian Lin
For some questions such as checking whether a number is odd or even, I noted the comment,
a & 1
won't work when it is a one's complement machine or when the code is ported to a platform that uses one's complement.
Since 30 years ago on the Superboard, TRS-80, Apple II, I haven't seen a system with one's complement.
Are there popular systems that use one's complement still, or do we have some cell phone or mobile device that uses one's complement?
