Hi there. What's the way to take a number from a TextField as a double number, not as a String. I know you can get it as a String with "textfieldName.getText()", but it does not work for me because I need to take the text in field as a number, of course assuming that what I write on the TextField will be only numbers. Maybe is there any kind of TextField but for numbers, or any way to convert a String with numbers into a double. Thanks!
