APPENDIX D

Representing Negative Integers

The industry standard method for representing negative integers is called two’s complement. Here is how it works:

For an integer represented using 16 bits, the leftmost bit is reserved for the sign bit. If the sign bit is 0, then the integer is positive; if the sign bit is 1, then the integer is negative.

For example, let’s consider two numbers, one positive and one negative.

0000 0101 0111 1001 is a positive integer, which we call a.

1111 1111 1101 1010 is a negative integer, which we will call b.

Using the methodology presented in Chapter 1 for converting a binary number to a decimal number, we can convert the binary number, a, to its decimal equivalent. Hence, the value of a is calculated as follows: ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
