MATLAB always keeps track of numbers to double precision regardless of
the output format. To alter the display of numbers, use **format**.
The argument **short** gives five digits (the default) and **long**
fifteen digits; a second argument of **e** to either switches to
floating-point.

Further, **format hex** gives hexadecimal, **format +** gives signs
*only*, **format bank** uses dollars and cents,
and **format rat** uses ratios of small integers as approximations.

Finally, **format compact** and **format loose** can be set independantly
of all the other formatting, and supress or allow, respectively, extra
linefeeds in output.
