Computer numbers and mathematics
For this course, we will only be concerned with fixed point numbers (representing integers) and floating point numbers (representing reals). Since computer represnetaions of numbers are finite, they are only approximations to the integer ring and real field of mathematics. This notebook presents a small list of things to be mindful of to avoid unexpected results.

The Julia language has a particularly friendly and comprehensive intorduction to computer arithmetic which is also appicable to Python.
