Answering Basic Assembly Language Questions - Assembly Language for Beginners @WhatsACreel

Uploaded July 2022 | Updated September 2026, 2 weeks ago

In this video we answer several basic questions regarding x86/64 Assembly Language programming. The language has a steep learning curve, but once the fundamentals are understood, the whole journey becomes an exploration of the capabilities of a modern CPU. I have tried to keep things fairly simple, but even the basics in Assembly can be fiddly and difficult without clear step-by-step explanations of what is happening in the CPU. I hope this video helps people new to the language, as well as hints at some of the awesome power and flexibility of the language :)

$Fixed Point Arithmetic 1: Intro to Fixed Point In this video well look at fixed point arithmetic. This is a technique for performing operations on numbers with fractional parts using integers, instead of the more common floating point. Fixed point has some pretty amazing benefits, depending on how and when it is used. We can use bytes, short ints, ints, or long integers, we can select the precision and range of our variables. Fixed point is very flexible and (sometimes) very fast. Its extremely good at certain types of tasks, for instance, working with image processing matrices. It can also do some things which floating point cannot, such as exactly represent 1/3 or 1/5. Fixed point is not a hack, its a fantastic tool to add to your belt if youve not yet come across it. If you have used fixed point in the past, I hope this tute is a good refresher! Also, I forgot to mention something in the tute: The technique I used to get the fractional part of the fixed point number literally gives us the bits that comprise the fractional part of the number. If your number is negative, then they will not be the correct bits if you print the fixed point to screen. Facebook: https://www.facebook.com/pages/WhatsaCreel/167732956665435$
