help you fix your problem I understand that there are rounding errors but can anyone explain why I get such different results using these different methods: , The second one should be
code :
var cost1 = (int)(amount * 1000);

this will help You need to assign delegate to your textfield and in the shouldChangeCharactersIn delegate method do your validations:
code :
extension String{

    private static let decimalFormatter:NumberFormatter = {
        let formatter = NumberFormatter()
        formatter.allowsFloats = true
        return formatter
    }()

    private var decimalSeparator:String{
        return String.decimalFormatter.decimalSeparator ?? "."
    }

    func isValidDecimal(maximumFractionDigits:Int)->Bool{

        // Depends on you if you consider empty string as valid number
        guard self.isEmpty == false else {
            return true
        }

        // Check if valid decimal
        if let _ = String.decimalFormatter.number(from: self){

            // Get fraction digits part using separator
            let numberComponents = self.components(separatedBy: decimalSeparator)
            let fractionDigits = numberComponents.count == 2 ? numberComponents.last ?? "" : ""
            return fractionDigits.characters.count <= maximumFractionDigits
        }

        return false
    }

}
func textField(_ textField: UITextField, shouldChangeCharactersIn range: NSRange, replacementString string: String) -> Bool {

    // Get text
    let currentText = textField.text ?? ""
    let replacementText = (currentText as NSString).replacingCharacters(in: range, with: string)

    // Validate
    return replacementText.isValidDecimal(maximumFractionDigits: 2)

}

I think the issue was by ths following , This is normal and intended. Decimal tracks significant digits, and the Decimal repr is intended to preserve significant digits. Decimal('3.3E+3') has two significant digits, while Decimal('3300') has four.

hop of those help? You're almost there - all you have to do is include a check that the string is not empty (which can be accomplished with a positive lookahead for .{1,10} right after the ^), and check that its first digit string has at most 10 characters (just use a {0,10} quantifier for the digits). Also note that [0-9] simplifies to \d.
In order to also exclude trailing dots, repeat the digit after the dot with {1,2} instead of {0,2}:
code :
^(?!$)\d{0,10}(?:\.\d{1,2})?$
