Fractions
In Chapter 1, the section

To toggle Fraction-display mode on and off, press

Fraction-display mode is turned off, the display reverts to the previous display
format set via the Display menu. Choosing another format via this menu also
turns off Fraction-display mode, if active.
Functions work the same with fractions as they do with decimal numbers –
except for RND, which is discussed later in this chapter.
The examples in this chapter all utilize RPN mode unless otherwise noted.
