A Scrolling the Screen Left and Right
The screen will show up to 14 characters when inputting with natural display. When you
input more than 14 characters, the screen will scroll automatically. If this happens, the
symbol will turn on to let you know that the expression runs off the left side of the display.
• While the symbol is turned on, you can use the
and scroll the screen.
• Scrolling to the left causes part of the expression to run off the right side of the display,
which is indicated by the ' symbol on the right. While the ' symbol is on the screen, you
can use the key to move the cursor to the right and scroll the screen.
A Using Values and Expressions as Arguments
When inputting with natural display, in certain cases you can use a value or an expression
that is enclosed in parentheses that you have already input as the argument of a scientifi c
function (such as ' ), the numerator of a fraction, etc. For the sake of explanation here,
a natural display function that supports the use of previously input values or parenthetical
expressions is called an "insertable natural display function".
Example: To insert the natural display function ' into the parenthetical expression in the
following calculation: 1 + (2 + 3) + 4
Note
• Not all natural display functions are insertable. Only the scientifi c functions for which
"Yes" appears in the column of the table under "Scientifi c Functions that Support Natural
Display" (page 16) are insertable.
• The cursor can be immediately to the left of a parenthetical expression, a numeric value,
or a fraction. Inserting an insertable function will make the parenthetical expression, value,
or fraction the argument of the inserted function.
• If the cursor is located immediately to the left of a scientifi c function, the entire function
becomes the argument of the inserted function.
