A Calculator (3): Practical Numerical Methods

In the last post, we verified and quantified the precision of the basic four functions (addition, subtraction, multiplication, and division), and now we can use them as a stepping stone for more complex functions. We can assume they will be available to us so our experimentation at this stage could simply use built-in C++ functions.

In this article, which is the third in a series, we will continue with the proof-of-concept, or pathfinding, research.

A Calculator

The idea for this project came about during a week of freezing winter arctic event here in Austin, Texas, with a failed power grid as well as government, while keeping close to a gas fireplace, the only source of heat and light, for a couple of days. With a weak internet over a phone data line, I could only do some preliminary searches and mainly work out various details on a writing pad, growing a feeling that the project may be personally exciting and practically doable.

I will try to post my progress over the coming weeks.
