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:

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.
