7 / 18 page IZ1242M 7 a. The position first pressed has preference, and no input is made to data set in the exponent section. b. When pressed as the first set number, it is regarded as 0 and • keys are pressed. c. Random as a 2ndF. Pressing this key shall display the random numbers. The range of random numbers is 0.000 – 0.999. 5. +/- a. In setting data in the mantissa section, this key reverses the code in the mantissa section. Similarly, for the exponent section, it reverses the code in the exponent section. b. For the operation result, this key reverse codes in the mantissa section. 6. + , - , ×, ÷, =, ( ) a. When the key operations are performed by these keys according to a numerical expression, a result of the operation is obtained according to mathematical priorities, priorities discriminated are: 1) 1 Variable function 2) Expression in ( ): (The most inner expression has priority in case of multiple parentheses) 3) y x , x √y 4) ×, ÷ 5) +, - b. Whenever the key is operated, the calculator discriminates the above priorities and holds the data and operation keys pending as required. This pending action is possible up to 6 times and 7 or more pending become error. c. (Key is accepted only immediately after CE, +, -, ×, ÷, yx, x√y, =, (keys and not accepted in all other cases. When this key is accepted, the displayed data is cleared to 0. When ( key is first accepted, the special display « ( ) » illuminates. When a parenthesis expression is completed ) and = keys or when it is cleared by the ON/C key, etc, or when errors are generated, the special display « ( ) » goes out. d. If it is within the allowable range of pending. ( can be input into any place in an expression as many times as desired. However, if the key is pressed continuously 16 times or more, it be comes error. e. From a viewpoint of numerical expression, even when the corresponding C key is not pressed, the operation is not executed if the «)» key is pressed. On the other hand, when the «(« key is pressed and the «=» key is pressed without pressing the corresponding «)» key, the operation is also completed according to the priority. 7. Memory calculation ( x → M, RM, M+ ) a. The memory register «M» used by these keys is a completely independent single memory. b. Display data is added to «M» (memory register) by M+ key. If data overflows at this time, the processing data is held. c. Display data is stored in «M» by x → M key. d. Contents of «M» is displayed by MR key. e. When any data except for 0 is stored in «M», the special display «M» illuminates. 8. π a. This key displays a rounded value (3.141592654) of a 12-digit value (3.14159265359) according to the set display format. b. A value that is used in a subsequent operation is the above the 12-digit value. |
