Math: Ruining Everything Since Forever

Let's take a tour of what standard math libraries. How are they useful? How are they implemented? Why is Python 3.5 round(2.5) 2.0? Why is (2**100) % 31 different than pow(2, 100, 31)? How does John Carmack's fast inverse square root work?

This is a fun romp into the world of prime numbers, bit twiddling, IEEE 754, and other things your grandparents warned you about.

We'll provide examples in many languages, e.g., Java, Python, JavaScript.
