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.

make sens, but is it possible to define global variable for precision of amount (as for ISODate https://github.com/jerome-laforge/rtp20022/commit/ac6fa8700c64570bc8c2e0866f2fc66affd78e50) 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
