Besides enable the following: entering numbers using the text field, presenting a number using the scientific notation, if it is too large to fit the single line text field, displaying a multi line text field (possibly with scroll bars) for editing large numbers that do not fit within the single line text field. reading/writing a number to/from a file using menu, storing/retrieving a number in/from a memory cell using dedicated buttons.
