This is the fourth in a series of videos about the binary number system which is fundamental to the operation of a digital electronic computer. In particular, this video covers the representation of real numbers using floating point binary notation. It begins with a description of standard scientific form in base 10 (as used by scientists and engineers to denote very large or very small values) because floating point binary notation is similar in principle to standard form. It then explains with examples how to convert both positive and negative floating point binary numbers into denary.
