It has been a while since I wrote the last post about this project. In the meantime, I was able to dedicate all my free time to work on the implementation. As I was making really good progress, the calculator started taking shape. My excitement grew and I just could not stop the work to write about it.

For as long as I remember, I had played with LEGOs. Those simple blocks would transform into complex objects whose final shape only existed in the supple thoughts of creative imagination. The kind of LEGO blocks we had while growing up were simple: 2x4, 2x2, 1x8. Anything unusual was rare and precious.

In the last post, we have verified and quantified the precision of the basic four functions (addition, subtraction, multiplication, and division), and now we can use them as a steppingstone. 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 research.

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.
