This diagram shows how the displayed fraction relates to nearby values — S means the exact numerator is "a little above" the displayed numerator, and

Tmeans the exact numerator is "a little below".

This is especially important if you change the rules about how fractions are displayed. (See "Changing the Fraction Display" later.) For example, if you force all fractions to have 5 as the denominator, then 2/3 is displayed as S + because the exact fraction is approximately 3.3333/5, "a little above" 3/5. Similarly, –2/3is displayed as S . +5 because the true numerator is "a little above" 3.

If you press zX{#} to view the VAR catalog, the ST annunciator doesn't indicate accuracy — it means you can use —and ˜to move through the list of variables. The accuracy isn't shown.

Sometimes an annunciator is lit when you wouldn't expect it to be. For example, if you enter 2 2/3, you see S  +, even though that's the exact number you entered. The calculator always compares the fractional part of the internal value and the 12–digit value of just the fraction. If the internal value has an integer part, its fractional part contains less than 12 digits–and it can't exactly match a fraction that uses all 12 digits.

Longer Fractions

If the displayed fraction is too long to fit in the display, it's shown with ... at the beginning. The fraction part always fits — the ... means the integer part isn't shown completely. To see the integer part (and the decimal fraction), proms and hold {(You can't scroll a fraction in the display.)
