  According to the present invention, a calculation method of a computer having an error notification function includes (A) a step of inputting a calculation formula composed of a plurality of calculation units, (B) a step of temporarily storing the calculation formula, C) comparing the arithmetic expression with a predetermined plurality of arithmetic rules forming an arithmetic error, searching for an error part in the arithmetic expression, and (D) recording the error part in the arithmetic expression stored for a while. And (E) displaying an arithmetic expression and displaying an error part in the arithmetic expression displayed by the error part marked.

  Refer to the block diagram of FIG. 1 for the computer having the error notification function of the present invention. It comprises an input unit 11, a storage unit 12, an arithmetic rule unit 13, a display unit 14 and a processing unit 15. Among them, the above-mentioned input unit 11 is used when a user inputs data or a control command to a computer to perform an operation or calculation. For example, the input unit 11 can input an arithmetic expression and execute it by the processing unit 15. The aforementioned arithmetic expression is composed of arithmetic units such as an operation source, an operator, a function, or a parameter. The aforementioned storage unit 12 stores the computer control program and inputs the arithmetic expression, the numerical value of the arithmetic process, and the arithmetic result. The display unit 14 displays the output data of the computer, and the output data includes the input arithmetic expression and the operation result.

  The arithmetic expression rule unit 13 has a plurality of arithmetic rules forming an operation error, for example, the following rules: [Rule 1] The divisor is 0, that is, “/ 0” appears in the arithmetic expression; [Rule 2] parentheses Asymmetry: The number of left and right parentheses in an arithmetic expression is different; [Rule 3] An illegal function parameter, that is, a parameter of a function in an arithmetic expression is not a type that the function can operate (for example, A in sin (45 + A) Is a variable and not a number). Based on the calculation rule forming the calculation error provided by the calculation formula rule unit 13, the calculation formula input by the user is compared with each rule to find the calculation formula error part and notify the user.

  FIG. 2 is a control flowchart of the computer having the above-described error notification function. First, the user inputs an arithmetic expression using the input unit 11 (step S201). Subsequently, the user presses the enter key to confirm the input of the arithmetic expression (step S202). The inputted arithmetic expression is temporarily stored in the storage unit 12 (step S203).

  In step S204, the processing unit 15 compares the arithmetic expression with the rules in the arithmetic expression rule unit 13, finds an error part in the arithmetic expression rule, and converts the error part into the arithmetic expression stored in the storage unit 12. Write down. Among them, when there is an error part in the inputted arithmetic expression, the processing unit 15 displays error information on the display unit 14 (step S205). Further, the arithmetic expression stored for a while in the storage unit 12 is taken out (step S206), and the error part is displayed in the displayed arithmetic expression by the error part marked (step S207), and the arithmetic expression error is indicated to the user. Inform the part to be formed. In addition, the processing unit 15 provides the presentation of the repair method according to the rules in the arithmetic formula rule unit 13 (step S209), and when the ENTER key is pressed after the completion of the repair, the arithmetic formula is executed again.

  In step S204, when the arithmetic expression and the rule in the arithmetic expression rule unit 13 are compared and the input arithmetic expression is determined to be accurate, the processing unit 15 starts executing the arithmetic expression. A target calculation unit to be calculated including elements, operators, functions, parameters, etc. is extracted (step S211). At the same time, this target calculation unit is written in the calculation formula stored for a while in the storage unit 12 (step S212). Further, the calculation is actually executed for the target calculation unit (step S213). During this calculation, if the numerical value of the calculation result exceeds the number of digits allowed by the processing unit 15 (step S214), steps S205 to S209 are executed, error information is displayed on the display unit 14 (step 205), and The arithmetic expression stored for a while is taken out from the storage unit 12 (step 206), and the part forming the digit over is displayed in the arithmetic expression displayed by the target arithmetic unit described (step S207). Present (step S208), and finally the user performs modification by the input unit 11 (step S209), and then presses the enter key to execute the calculation formula again, and further overlaps the above calculation steps. Do.

  As in step S214 described above, the numerical value of the calculation result is determined, and if the number of digits allowed by the processing unit 15 is not exceeded, steps S211 to S213 are subsequently executed. When the calculation is completed, the result is displayed on the display unit 14. indicate.

  FIG. 3 shows an example in which an arithmetic expression is input to a computer having an error notification function of the present invention to perform the calculation. Among them, the arithmetic expression that the user inputs is ((10 + 8) / 0) × (4 + 9). After the user presses the enter key, the processing unit 15 compares the arithmetic expression with the rule in the arithmetic expression rule unit 13 and finds that there is an error of “/ 0” in the arithmetic expression. Error information is displayed on the display unit 14 (B in FIG. 3). The processing unit 15 further displays the part of “/ 0” in the black and white reversal or flicker method (C in FIG. 3) and presents the repair method (D in FIG. 3). Further, the user performs the repair using the input unit 11 (E in FIG. 3). When the user further presses the enter key after the repair is completed, the arithmetic expression is executed again to obtain an accurate result (F in FIG. 3).

  FIG. 4 shows an example of a calculation performed by a computer having another error notification function of the present invention. Of these, 99 users can enter 99! / 256 (A in FIG. 4). After the user presses the enter key, the processing unit 15 compares the arithmetic expression with the rules in the arithmetic expression rule unit 13 and finds that there is no error in this arithmetic expression. As a result, the execution of the arithmetic expression is started, the target arithmetic units “99” and “!” Are first taken out and recorded, and the arithmetic operation is actually executed on “99!”. Since the allowable number of digits of 15 is exceeded, error information (B in FIG. 4) is displayed on the display unit 14. The processing unit 15 further displays the part of “99!” In the calculation formula in black and white inversion or flickering method (C in FIG. 4) and presents the repair method (D in FIG. 4). Further, when the user performs the repair using the input unit 11 (E in FIG. 4) and further presses the enter key after the repair is completed, the arithmetic expression is executed again to obtain an accurate result (F in FIG. 4).
