Is there a mock library works with generics?
https://github.com/derision-test/go-mockgen, we use this widely at work
-
Libraries you use most of your projects?
https://github.com/derision-test/go-mockgen for generating mocks for interfaces, for those that use dependency injection. By far the best mock generator, especially compared to the relatively bad official one, or anything that requires passing method names as strings...
-
What are your favorite packages to use?
https://github.com/derision-test/go-mockgen for the best mocks Ive ever had in Go https://github.com/go-chi/chi for HTTP routing

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.
