Which UIKeyboardType can I use on the iPad

I have a a textField object in my iPad app. I would like to give the user a convenient keyboard for entering numbers. In my code I added:

UITextField *textField = [[UITextField alloc] initWithFrame:frame];
textField.keyboardType = UIKeyboardTypeDecimalPad;

According to the docs this is a valid keyboard type but when I edit the text field the normal ASCII keyboard comes up. However, when I change it to: 

textField.keyboardType = UIKeyboardTypePhonePad;

The keyboard looks like this: phonepad keyboard

Ideally I would like a keyboard that only has the numbers and decimal point but is this not possible on the iPad? Does anyone have a definitive list of which keyboards work on the iPhone vs. iPad? Apple is unclear on this point. I also saw this question which is similar but none of the answers really address my point.
