around this issue
I want to remove everything to return the price only so it returns:
import re

s = "this is a value £28.99 (0.28/ml)"

m = re.search("£\d*(\.\d+)?",s)
if m:

Iphone keyboard with numbers, decimal point and minus sign

this one helps. No.
What you can do is use the UIKeyboardTypeDecimalPad keyboard type to get the numbers and decimal point.

How to multiply decimal numbers without using multiplication(*) sign

With these it helps Bit of a cheat, but if the task strictly relates to all forms of multiplication (rather than just the * operator), then divide by the reciprocal:
var result = first / (1 / (decimal)second);

Locale aware edit control subclassing for decimal numbers ( format [sign] [xxx...] [decimal separator] [yy...] )

hope this fix your issue Taking into consideration locale-specific settings
You certainly can do everything yourself, however you have an option to use VarI4FromStr or similar API which does dirty stuff for you. You put string in, you get LONG out. Locale aware.

Limit Text Field to one decimal point input, numbers only, and two characters after the decimal place - Swift 3

this will help You need to assign delegate to your textfield and in the shouldChangeCharactersIn delegate method do your validations:
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)


Remove all special characters except numbers and decimal points in ruby

Hope that helps Normally, a special character would be anything other than alphanumeric characters. If your own definition is the same then you need a regex to capture decimal numbers to save them from being removed:
re = /(\d\.\d)|[^a-zA-Z\d]/
str = 'test1.3eb@j$2.xyz.'
subst = '\\1'

result = str.gsub(re, subst)

puts result
