How to keep original double value while parsing in json swift?

Question

I received the following response from server

"transactionInfo": {
      "currencyCode": "MYR",
      "total": 472.23,
      "roomCurrencyCode": "MYR",
      "roomTotal": 472.23
}

but when I am trying to convert using SwiftyJson and map using below code

struct TransactionInfoModel: Codable {
   var currencyCode: String
   var total: Double
   var roomCurrencyCode: String
   var roomTotal: Double
}

then I get values like below:

"currencyCode": "MYR",
"total": 472.23000000000002,
"roomCurrencyCode": "MYR",
"roomTotal": 472.23000000000002

Please suggest how to resolve this issue. Thanks in advance.

Double can’t represent certain values exactly. Use Decimal, slower but safer for financial data – Escarpment
