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).

What libraries are missing?
https://github.com/cockroachdb/apd is currently the best implementation in the ecosystem (performance, correctness). Have you already evaluated it?

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).
-
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.
