Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Library recommendation -- money calculations, more accurate handling of floats
I am still tracking ericlagergren/decimal as an alternative to apd, due to its better performance, but it's still seeing very low maintainer activity (still waiting on a v4 for go mod compat).
-
currency - Currency amounts and formatting for Go
Note: In benchmarks ericlagergren/decimal was noticeably faster than cockroachdb/apd, but it has known bugs when used with go mod, so I decided to wait and go with cockroachdb/apd for now. The Amount struct wraps the decimal implementation completely, making it easy to do the swap later without breaking BC.

What libraries are missing?
https://github.com/cockroachdb/apd is currently the best implementation in the ecosystem (performance, correctness). Have you already evaluated it?
-
Lack of Decimal Support
FWIW I think cockroachdb/apd is the best third party option. While building bojanz/currency I've evaluated and benchmarked the others and found them either less maintained, slower, or both.
-
Small Fixed-Point Decimals library
I have a package for handling currency amounts and calculations that is based on cockroachdb/apd, in my opinion the best arbitrary-precision decimal implementation in Go right now. So, I can offer a bit of insight.
- cockroachdb/apd v3.0.0
-
Library recommendation -- money calculations, more accurate handling of floats
The best decimal package is still cockroachdb/apd. I wrap it in bojanz/currency for money handling.
-
What libraries from other languages do you wish were ported over into go?
https://github.com/cockroachdb/apd remains the best decimal library for Go (ericlagergren/decimal is faster but unmaintained).
