Signed and Unsigned Numbers Made Easy! – Bits, Bytes & Binary Numbers

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. “CODE WITH HUW” ON TWITTER: =================================   / codewithhuw   “CODE WITH HUW” ON FACEBOOK: =================================   / codewithhuw   Good luck!
