It would be nice if Decimal types implemented the fmt.Formatter interface to allow the use of standard fmt verbs/flags when formatting decimals to strings.

For example:

fmt.Printf("%.2f", decimal.RequireFromString("3.14"))

Would be equivalent to:

fmt.Printf("%s", decimal.RequireFromString("3.14").StringFixed(2))

There are a number of other verbs/flags that could be implemented which can be seen here
