JSONSerialization works differently on platforms

[Ildarec11]

If you run the following code on macOS, the output will be 68.31999999999999:

let jsonString = """
{
    "amount": 68.32
}

let json = jsonString.data(using: .utf8)!
let serialized = try JSONSerialization.jsonObject(with: json) as! [String: Any]

let amount = serialized["amount"]
print(amount)

However, if you run the same code on SwiftFiddle (using the x86_64-unknown-linux-gnu platform), the output will be 68.32.
