2. Type 2^8 to begin the expression. 3. Press ¢ to return the cursor to the baseline, and then type r 43 p 12. 4. Press · to evaluate the expression. The expression displays in standard mathematical notation, and the result displays on the right side of the Calculator. Note: If a result does not fit on the same line with the expression, it displays on the next line. Controlling the form of a result You might expect to see a decimal result instead of 2752/3 in the preceding example. A close decimal equivalent is 917.33333..., but that's only an approximation. By default, Calculator retains the more precise form: 2752/3. Any result that is not a whole number displays in a fractional form. This reduces rounding errors that could be introduced by intermediate results in chained calculations. You can force a decimal approximation in a result: • By pressing / · instead of · to evaluate the expression. Pressing / · forces approximate result. • By including a decimal in the expression (for example, 43. instead of 43). Using Calculator 61

Controlling the form of a result
You might expect to see a decimal result instead of 2752/3 in the
preceding example. A close decimal equivalent is 917.33333..., but that’s
only an approximation.
By default, Calculator retains the more precise form: 2752/3. Any result
that is not a whole number displays in a fractional form. This reduces
rounding errors that could be introduced by intermediate results in
chained calculations.
You can force a decimal approximation in a result:
•
By pressing
/·
instead of
·
to evaluate the expression.
•
By including a decimal in the expression (for example,
43.
instead of
43
).
Pressing
/·
forces approximate result.
