Input of the tolerance (tol) value and the closing parenthesis can be omitted. Specify a tolerance (tol) value of 1E14 or greater. An error (Time Out) occurs whenever no solution that satisfies the tolerance value can be obtained. The rules that apply for linear differential also apply when using a quadratic differential calculation for the graph formula (see page 2-24). Inaccurate results and errors can be caused by the following: - discontinuous points in x values - extreme changes in x values - inclusion of the local maximum point and local minimum point in x values - inclusion of the inflection point in x values - inclusion of undifferentiable points in x values - differential calculation results approaching zero You can interrupt an ongoing quadratic differential calculation by pressing the key. Always use radians (Rad mode) as the angle unit when performing trigonometric quadratic differentials. You cannot use a differential, quadratic differential, integration, , maximum/minimum value, Solve, RndFix or logab calculation expression inside of a quadratic differential calculation term. With quadratic differential calculation, calculation precision is up to five digits for the mantissa. In the Math input/output mode, the tolerance value is fixed at 1E10 and cannot be changed.

7. Binary, Octal, Decimal, and Hexadecimal Calculations with Integers
You can use the RUN MAT (or RUN) mode and binary, octal, decimal, and hexadecimal settings to perform calculations that involve binary, octal, decimal and hexadecimal values. You can also convert between number systems and perform bitwise operations. You cannot use scientific functions in binary, octal, decimal, and hexadecimal calculations. You can use only integers in binary, octal, decimal, and hexadecimal calculations, which means that fractional values are not allowed. If you input a value that includes a decimal part, the calculator automatically cuts off the decimal part. If you attempt to enter a value that is invalid for the number system (binary, octal, decimal, hexadecimal) you are using, the calculator displays an error message. The following shows the numerals that can be used in each number system. Binary: 0, 1 Octal: 0, 1, 2, 3, 4, 5, 6, 7 Decimal: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Hexadecimal: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F Negative binary, octal, and hexadecimal values are produced using the twos complement of the original value. The following are the display capacities for each of the number systems.

Graphing a Phase Plot from Two Numeric Sequences

Inputting Text into a Cell
To input text, make sure the first thing you input into the cell is (). The quote mark (") tells the calculator that what follows is text, and should be displayed as-is without calculation. The quote mark (") is not displayed as part of the text.
Inputting a Formula into a Cell
For the sake of example, lets try making a table that contains data based on the formula <PRICE> <QUANTITY> = <TOTAL>. To do this, we would put <PRICE> values in column A, <QUANITY> values in column B, and calculation formulas (like = A1 B1, = A2 B2, and so on) in column C. If the Auto Calc feature is enabled (On), the values in column C would be recalculated and updated any time we change the values in column A or B. In this example, note that we must start out the data in column C with the equal sign in order to indicate it is a formula. In addition to values, arithmetic operators, and cell reference names, a formula also can contain built-in function commands (page 2-11) and special S SHT mode commands (page 9-14).

Formula Input Example

A Procedure 1. Input the text for line 1, and the applicable values in cells A2 through B4. 2. Move the cursor to cell C2, and input the formula for A2 (A) (B) B2. PRICE 78 B QUANTITY 20 C TOTAL 1560
3. Copy the formula in cell C2 and copy it into cells C3 and C4. Move the cell cursor to cell C2 and then perform the following operation. (EDIT) (COPY) (PASTE) (PASTE) For details about the copy and paste operations, see Copying and Pasting Cell Contents (page 9-10).
Inputting a Cell Reference Name
Each cell on a spreadsheet has what is called a reference name, which is derived by combining its column name (A through Z) with its row name (1 through 999). A cell reference name can be used inside of a formula, which makes the value of the called cell part of the formula. See Inputting a Formula into a Cell above for more information. There are two methods you can use to input a cell reference name: direct input of the name and input using the GRAB command. The following illustrates how you would use each of these methods to input =A1+5 into cell B1.

File Memory (File 1 to File 6)
Matrix Memory (Mat A ~ Mat Z)
The following describes what happens if you try to store data in memory when a cell does not contain any data, when a cell contains text, or when ERROR is displayed for a cell. If you are assigning data to a variable, an error occurs. If you are storing data in list memory, file memory, or matrix memory, 0 is written into the applicable cell(s).
Example: To store column data in list memory
1. In a single column, select the range of cells you want to store in list memory. For example, you could select A1:A10. 2. Press ( ) (STO) (LIST). This will display a screen like the one shown to the right. The Cell Range setting will show the range of cells you selected in step 1. 3. Press to move the highlighting to List[1-26]. 9-20
4. Input the List number (1 to 26) of the list memory where you want to store the data and then press. Performing the next step will overwrite any data currently stored under the list memory number you specified here with the data in the range of cells specified by CellRange. 5. Press (EXE) or the key to store the data.
Recalling Data from Memory to a Spreadsheet
The following table shows an overview of the recall operations for each type of memory. For details about each operation, see the example operations following the table.

Handling Precautions

Your calculator is made up of precision components. Never try to take it apart. Avoid dropping your calculator and subjecting it to strong impact. Do not store the calculator or leave it in areas exposed to high temperatures or humidity, or large amounts of dust. When exposed to low temperatures, the calculator may require more time to display results and may even fail to operate. Correct operation will resume once the calculator is brought back to normal temperature. The display will go blank and keys will not operate during calculations. When you are operating the keyboard, be sure to watch the display to make sure that all your key operations are being performed correctly. Replace the main batteries once every one year regardless of how much the calculator is used during that period. Never leave dead batteries in the battery compartment. They can leak and damage the unit. Do not use an oxyride battery* or any other type of nickel-based primary battery with this product. Incompatibility between such batteries and product specifications can result in shorter battery life and product malfunction. Keep batteries out of the reach of small children. If swallowed, consult a physician immediately. Avoid using volatile liquids such as thinner or benzine to clean the unit. Wipe it with a soft, dry cloth, or with a cloth that has been moistened with a solution of water and a neutral detergent and wrung out. Always be gentle when wiping dust off the display to avoid scratching it. In no event will the manufacturer and its suppliers be liable to you or any other person for any damages, expenses, lost profits, lost savings or any other damages arising out of loss of data and/or formulas arising out of malfunction, repairs, or battery replacement. It is up to you to prepare physical records of data to protect against such data loss. Never dispose of batteries, the liquid crystal panel, or other components by burning them. Be sure that the power switch is set to OFF when replacing batteries. If the calculator is exposed to a strong electrostatic charge, its memory contents may be damaged or the keys may stop working. In such a case, perform the Reset operation to clear the memory and restore normal key operation. If the calculator stops operating correctly for some reason, use a thin, pointed object to press the RESTART button on the back of the calculator. Note, however, that this clears all the data in calculator memory. Note that strong vibration or impact during program execution can cause execution to stop or can damage the calculators memory contents.
