Approximating Euler’s Constant From Scratch

Or: Calculus You Will Use Either Every Day or Never
Approximating Constants
We will be calculating Euler’s constant, e, by starting off close to the correct value, and then moving closer and closer until we get to the correct value. This is known as approximation.
There are a few different ways to do this. A few are listed [...]

Quake 3’s Fast Inverse Square Root Function

Note: This is not meant to be an authoritative mathematical description, and I’m pretty late to the party.. I was experimenting with the code, and am scratching an itch. For a far superior description, please look at Chris Lomont’s excellent analysis.
The Infamous Code

x2 = number * 0.5F;
y = number;
i = * ( long [...]
