<p> Besides digits, numerical input can include a negative sign(-50), dollar sign ($50.25),
decimal point (.), exponential (1.15e+25) or a real number with a division slash (1/2 or 9 3/4).

<p> If you are expressing a positive integer you can return an ordinal number-
that is, 21 converts to "twenty first" and 12 to "twelfth". Check the "Ordinal" box for this.
