Basic Calculations

Chapter 2

8. Fraction Calculations

(1) Fraction Display and Input

 Example 1 Display of

 Example 2 Display of 3

Mixed fractions (such as 3 1/4) are input and displayed as:
integer

{

numerator

{

denominator.

Improper fractions (15/7) and proper fractions (such as 1/4) are input and displayed
as: numerator

{

denominator.

Use the 

$

 key to input each part of a fraction.

Note that the maximum size of a fractional value is 10 digits, counting the integer,
numerator, and denominator digits and separator symbols. Any value longer than
10 digits is automatically converted to its equivalent decimal value.
