rtp.Amount trim trailing zero (or not force the decimal part)

[jerome-laforge]

Hello,
Is it possible to not force the decimal part of rtp.Amount?
Because some currencies:

• don't have decimal part (i.e. XOF, XAF)
• have more than 2 digits on decimal part (more unusual...)

This repository is used for RTP (by The Clearing House) which only allows USD. They don't support all of the currencies that ISO 20022 does.

Edit: See #47 (comment) for more details on how to support these differences.

make sens, but is it possible to define global variable for precision of amount (as for ISODate jerome-laforge@ac6fa87) with default value set to 2 (current behavior for USD) ?

	f := 1.5
	fmt.Println(strconv.FormatFloat(f, 'f', -1, 64)) // 1.5 no trailling zeros
	fmt.Println(strconv.FormatFloat(f, 'f', 2, 64))  // 1.50 
	fmt.Println(strconv.FormatFloat(f, 'f', 3, 64))  // 1.500
