Fractions
In Chapter 1, the section Fractions introduced the basics of entering, displaying,
and calculating with fractions. This chapter gives more information on these topics.
Here is a short review of entering and displaying fractions:
 To enter a fraction, press
 twice: once after the integer part of a mixed
number and again between the numerator and denominator of the fractional
part of the number. To enter 2 3/8, press
. To enter 5/8,
press either  or .
 To toggle Fraction-display mode on and off, press
. When
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.
Entering Fractions
You can type almost any number as a fraction on the keyboard — including an
improper fraction (where the numerator is larger than the denominator).
