Numbers that are signed (can
Numbers that are signed (can have positive or negative values) have different ranges of values from numbers that are unsigned (positive only values) and it’s all down to a simple 1 or 0 – the vaklue of the leftmost bit in a byte. Why is that?
In this lesson, I explain exactly how each bit contributes a value to a given number and how that value can be switched from plus to minus. I also return to a problem I looked at some time ago: why do big positive numbers sometimes get changed to negative?

PROGRAMMING BOOKS
====================
If you want to learn programming in more depth (and also support this channel!) you might think of buying one of my books. I have written books on C programming, Using Pointers in C, Recursion and other programming topics. You can buy my books (paperback or Kindle) on Amazon.
