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.

Trouble understanding rounding when the next digit is after round precision is a #5?
Try it in JS with console.log(4.225 * 100);, you'll see the same unexpected result. Depending on your needs, it's actually fine to just be off by some amount. If it does really matter, then use an arbitrary precision library like https://github.com/shopspring/decimal to get the results you need.

Handling currency values: facts and best practices
Most programming languages ( JavaScript, PHP, Go, Python, Java, C# ) have built-in support or 3rd-party libraries for handling this data type, even though the internal implementations can differ:

Any go and python number experts here?
while working with money, dont use floats, use something like https://github.com/shopspring/decimal (go std lib doesnt have its own decimals yet)

my first golang project!
Integers, or something like this: https://github.com/shopspring/decimal

80x improvements in caching by moving from JSON to gob
I make heavy use of caching, and was caching both in-memory and in Redis using JSON to convert the data in to a string. The struct itself isn't super complicated, one level nested, and some fields use the shopspring/decimal library.

Unexported interfaces usage question
I actually use this to represent monetary values btw :)

How to round(2) float64?
Check out https://github.com/shopspring/decimal for doing money related calculations.

Library recommendation -- money calculations, more accurate handling of floats
We personally use https://github.com/shopspring/decimal and it works well.

What are your favorite packages to use?
decimal, one of the first Go library that created to work with decimal and monetary value.

What libraries from other languages do you wish were ported over into go?
https://github.com/shopspring/decimal also.

Should golang create a money library on the exp package?
I maintain a decent solution in this problem space: https://github.com/bojanz/currency

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.

Golang E-Commerce framework
Yes, MySQL/MariaDB have a decimal column type that should be used. I have an example of that here.
-
cockroachdb/apd v3.0.0
Did some benchmarks for bojanz/currency, after switching it to v3. The performance increase is noticeable.
-
Library recommendation -- money calculations, more accurate handling of floats
I have the change done in a branch, I just need 4.0.0 to be released, but it's been a long wait (I opened https://github.com/bojanz/currency/issues/1 in May of 2020).
