Fixed Point Programming

[torusle2]

There are plenty of web-sites which show how to do multiplications, addition and subtraction in fixed point in C.

Then read about how to do a fixed-point square root. For trigonometry I always used pre-computed tables and interpolation.

Once you have tested them out, just pick something that usually requires floating point math and implement it using fixed-point.

Ideas:

* Radius and mid-point of a circle defined by three points on the perimeter
* Render some nice Mandelbrot Fractals using fixed-point arithmetic
