I'll create a digital keypad design with support for negative numbers, a title, and confirm/cancel buttons.

This design includes:

1. A title at the top ("数字输入" - Number Input)
2. A display area showing the current value
3. Numeric keypad with digits 0-9
4. A "+/-" button to toggle between positive and negative numbers
5. A decimal point button for decimal values
6. A backspace button to delete the last digit
7. A clear button to reset the input
8. "取消" (Cancel) and "确认" (Confirm) buttons at the bottom

The component maintains the current value and negative state, allowing users to enter both positive and negative numbers. When the confirm button is pressed, it will log the final value (with the appropriate sign).
