Rnd : The argument of this function is made a decimal value and then rounded in accordance with the current number of display digits setting (Norm, Fix, or Sci). With Norm 1 or Norm 2, the argument is rounded off to 10 digits. With Fix and Sci, the argument is rounded off to the specified digit. When Fix 3 is the display digits setting, for example, the result of is displayed as 3.333, while the calculator maintains a value of 3.33333333333333 (15 digits) internally for calculation. In the case of Rnd(103) = 3.333 (with Fix 3), both the displayed value and the calculators internal value become 3.333. Because of this a series of calculations will produce different results depending on whether Rnd is used (Rnd(103) 3 = 9.999) or not used (3 = 10.000). See 17. Note: Using functions can slow down a calculation, which may delay display of the result. Do not perform any subsequent operation while waiting for the calculation result to appear. To interrupt an ongoing calculation before its result appears, press.
Integration and Differential Calculation Precautions
Integration and differential calculations can be performed in the COMP Mode ( ) only. The following cannot be used in f(x), a, b, or tol: Pol, Rec, , d/dx,. When using a trigonometric function in f(x), specify Rad as the angle unit. A smaller tol value increases precision, but it also increases calculation time. When specifying tol, use value that is or greater. Precautions for Integration Calculation Only Integration normally requires considerable time to perform. 1 For f(x) 0 where a x b (as in the case of 0 3x= 1), calculation will produce a negative result. Depending on the content of f(x) and the region of integration, calculation error that exceeds the tolerance may be generated, causing the calculator to display an error message. Precautions for Differential Calculation Only If convergence to a solution cannont be found when tol input is omitted, the tol value will be adjusted automatically to determine the solution. Non-consecutive points, abrupt fluctuation, extremely large or small points, inflection points, and the inclusion of points that cannot be differentiated, or a differential point or differential calculation result that approaches zero can cause poor precision or error.
Tips for Successful Integration Calculations
When a periodic function or integration interval results in positive and negative f(x) function values Perform separate integrations for each cycle, or for the positive part and the negative part, and then combine the results.

To exit SOLVE:
Note: During the time from when you press (SOLVE) until you exit SOLVE by pressing , you should use Linear Display input procedures for input. Important: Depending on what you input for the initial value for X (solution variable), SOLVE may not be able to obtain solutions. If this happens, try changing the initial value so they are closer to the solution. SOLVE may not be able to determine the correct solution, even when one exists. SOLVE uses Newtons Law, so even if there are multiple solutions, only one of them will be returned. Due to limitations in Newtons Law, solutions tend to be difficult to obtain for equations like the following: y = sin(x), y = ex, y = '. x

k Start, End, and Step Value Rules
Linear format is always used for value input. You can specify either values or calculation expressions (which must produce a numeric result) for Start, End, and Step. Specifying an End value that is less than the Start value causes an error, so the number table is not generated. The specified Start, End, and Step values should produce a maximum of 30 x-values for the number table being generated. Executing a number generation table using a Start, End, and Step value combination that produces more than 30 x-values causes an error. E-61
Certain functions and Start, End, Step value combinations can cause number table generation to take a long time.

k Number Table Screen

The number table screen shows x-values calculated using the specified Start, End, and Step values, as well as the values obtained when each x-value is substituted in the function f(x). Note that you can use the number table screen for viewing values only. Table contents cannot be edited. Pressing the A key returns to the function editor screen.

k TABLE Mode Precautions

Note that changing the input/output format settings (Math format or Linear format) on the calculators setup screen while in the TABLE Mode clears the number table generation function.

Precision is basically the same as that described under Calculation Range and Precision, above. y ^(xy), x', 3', x!, nPr, nCr type functions require consecutive internal calculation, which can cause accumulation of errors that occur with each calculation. Error is cumulative and tends to be large in the vicinity of a functions singular point and inflection point.

k Error Messages

The calculator will display an error message when a result exceeds the calculation range, when you attempt an illegal input, or whenever any other similar problem occurs.
When an error message appears.
The following are general operations you can use when any error message appears. Pressing d or e displays to the calculation expression editing screen you were using before the error message appeared, with the cursor located at the position of the error. For more information, see Displaying the Location of an Error. Pressing A clears the calculation expression you input before the error message appeared. You can then re-input and re-execute the calculation, if you want. Note that in this case, the original calculation will not be retained in calculation history memory.

Math ERROR

Cause The intermediate or final result of the calculation you are performing exceeds the allowable calculation range. Your input exceeds the allowable input range (particularly when using functions). The calculation you are performing contains an illegal mathematical operation (such as division by zero). Action Check the input values, reduce the number of digits, and try again. When using independent memory or a variable as the argument of a function, make sure that the memory or variable value is within the allowable range for the function.

Stack ERROR

Cause The calculation you are performing has caused the capacity of the numeric stack or the command stack to be exceeded. The calculation you are performing has caused the capacity of the matrix stack to be exceeded. The calculation you are performing has caused the capacity of the vector stack to be exceeded. Action Simplify the calculation expression so it does not exceed the capacity of the stack. Try splitting the calculation into two or more parts.

Syntax ERROR

Cause There is a problem with the format of the calculation you are performing. Action Make necessary corrections.

Argument ERROR

Cause There is a problem with the argument of the calculation you are performing.
Action Make necessary corrections.
Dimension ERROR (MATRIX and VECTOR Modes only)
Cause The matrix or vector you are trying to use in a calculation was input without specifying its dimension. You are trying to perform a calculation with matrices or vectors whose dimensions do not allow that type of calculation. Action Specify the dimension of the matrix or vector and then perform the calculation again. Check the dimensions specified for the matrices or vectors to see if they are compatible with the calculation.
Variable ERROR (SOLVE feature only)
Cause You did not specify a solution variable, and there is no X variable in the equation you input. The solution variable that you specified is not included in the equation you input. Action The equation you input must include an X variable when you do not specify the solution variable. Specify a variable that is included in the equation you input as the solution variable.
Cant Solve Error (SOLVE feature only)
Cause The calculator could not obtain a solution. Action Check for errors in the equation that you input. Input a value for the solution variable that is close to the expected solution and try again.

Insufficient MEM Error

Cause There is not enough memory to perform your calculation. Action Narrow the table calculation range by changing the Start, End, and Step values, and try again.

Time Out Error

Cause The current differential or integration calculation ends without the ending condition being fulfilled. Action Try increasing the tol value. Note that this also decreases solution precision.
k Before assuming malfunction of the calculator.
Perform the following steps whenever an error occurs during a calculation or when calculation results are not what you expected. If one step does not correct the problem, move on to the next step. Note that you should make separate copies of important data before performing these steps. (1) Check the calculation expression to make sure that it does not contain any errors. (2) Make sure that you are using the correct mode for the type of calculation you are trying to perform. (3) If the above steps do not correct your problem, press the O key. This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. For details about initialized settings, see Initializing the Calculation Mode and Other Settings under Calculation Modes and Calculator Setup. (4) Initialize all modes and settings by performing the following operation: 19(CLR) 1(Setup) =(Yes).
