When this library was first revealed, I had expressed concerns about the very beginning of the documentation, the Motivation and Use Cases sections. Matt seemed to agree in part, but I see that not much has been changed there.
Do you have specific suggestions? I reworded and expanded the since you raised concerns last time.
My suggestion to add some authoritative references was adopted, thats nice. A function for rounding to a given number of decimal figures (i.e. cents/satoshis) is still absent.
It was added a bit back after your request. See: https://cppalliance.org/decimal/decimal.html#cmath_trunc_to.
The other thing still missing is usage examples in the domain where this library is actually meant to be useful, financial calculations, and calculator/spreadsheets software. I am writing this in the hope that documentation will be improved even before the review starts.
Yes, we will continue to beef up the examples section in the coming weeks. Matt
