Fractions In The Display; Display Rules - HP 35s User Manual

If you didn't get the same results as the example, you may have accidentally
changed how fractions are displayed. (See "Changing the Fraction Display" later in
this chapter.)
The next topic includes more examples of valid and invalid input fractions.

Fractions in the Display

In Fraction–display mode, numbers are evaluated internally as decimal numbers,
then they're displayed using the most precise fractions allowed. In addition,
accuracy annunciators show the direction of any inaccuracy of the fraction
compared to its 12–digit decimal value. (Most statistics registers are exceptions —
they're always shown as decimal numbers.)

Display Rules

The fraction you see may differ from the one you enter. In its default condition, the
calculator displays a fractional number according to the following rules. (To change
the rules, see "Changing the Fraction Display" later in this chapter.)
The number has an integer part and, if necessary, a proper fraction (the
numerator is less than the denominator).
The denominator is no greater than 4095.
The fraction is reduced as far as possible.
Examples:
These are examples of entered values and the displayed results. For comparison, the
internal 12–digit values are also shown. The
column are explained below.
