						 <p>Almost two years later, I remembered I still had a draft for this page. I worked on it a bit and it isn't as complete as I hope for it to eventually be, but at least it is better :)</p>

						 <p>I've begun the process of updating it. It's going to be a total overhaul, so I've been editing a draft of the new page. It is going to be a while :|</p>

						 <p>It has been years since I updated this and some of these routines are making me cringe (and some I'm fairly sure are wrong). This page needs a serious update at some point when I get time and I'm not using a phone.</p> <p>I must have been practically a heathen when I made these routines XD</p> <p>I have better algorithms and faster codes, comment if you need something or if I forget to edit.</p>

						 <p>I realised many people won't see that I am actually editing pages and adding to them unless they are watching the site, but might notice discussions. For anybody in need of advanced math routines, I have added to this page:</p> <p><strong>Integer</strong> multiplication, division<br /> <strong>Fixed Point</strong> Addition, subtraction, multiplication, division, 2<sup>x</sup>, ln(x), log<sub>2</sub>(x), arctan(x), sin(x), square root<br /> <strong>Table Based fixed point</strong> arctan, lg(), and ln()<br /> A decent pseudo-random number generator (PRNG)</p> <p>I also have a collection of <a href="https://drive.google.com/folderview?id=0B4HNIXQZLWM8Z3NQMGJTbHVhRm8&amp;usp=sharing">Floating Point Routines</a> that I have been working on as well, some of which provide better accuracy than the OS ;)</p>
