allowable height of a calculation formula is two display screens (31 dots × 2).
Further input will become impossible if the height of the calculation you are
inputting exceeds the allowable limit. • Nesting of functions and parentheses
is allowed. Further input will become impossible if you nest too many functions
and/or parentheses. If this happens, divide the calculation into multiple parts
and calculate each part separately.
Note: When you press = and obtain a calculation result using Natural
Display, part of the expression you input may be cut off. If you need to view
the entire input expression again, press A and then use d and e to
scroll the input expression.
Using Values and Expressions as Arguments
(Natural Display only)
A value or an expression that you have already input can be used as the
argument of a function. After you have input
it the argument of ', resulting in
To input 1 + 7
As shown above, the value or expression to the right of the cursor after
1Y(INS) are pressed becomes the argument of the function that is
specified next. The range encompassed as the argument is everything up
to the first open parenthesis to the right, if there is one, or everything up to
the first function to the right (sin(30), log2(4), etc.)
This capability can be used with the following functions: ', 1'((),
16("), 1l($), 1i(%), !, 6, 1!(#), D.
Overwrite Input Mode
You can select either insert or overwrite as the input mode, but only while
Linear Display is selected. In the overwrite mode, text you input replaces the
text at the current cursor location. You can toggle between the insert and
overwrite modes by performing the operations: 1Y(INS). The cursor
appears as "
" in the insert mode and as " " in the overwrite mode.
Note: Natural Display always uses the insert mode, so changing display
format from Linear Display to Natural Display will automatically switch to
the insert mode.
Correcting and Clearing an Expression
To delete a single character or function: Move the cursor so it is directly to
the right of the character or function you want to delete, and then press Y.
In the overwrite mode, move the cursor so it is directly under the character
or function you want to delete, and then press Y.
To insert a character or function into a calculation: Use d and e to
move the cursor to the location where you want to insert the character or
and then change it to 1 +
(Linear Display only)
6 , for example, you can make
1 + 7 ' 6
