It is possible to specify the number of 0 to 9 digits below the decimal place by assignment of the decimal digit. Classification of operating mode The following 6 types of operation mode are set by the 2ndF key and below keys: 2ndF 2ndF 2ndF 2ndF 2ndF 2ndF STAT CLPX - BIN - OCT - HEX - DEC : Statistic calculation mode set : Complex number calculation mode set : Binary mode set : Octal mode set : Hexadecimal mode set : Decimal mode set 2 IZ1242C Kinds of keys and classification of the multi-functions for all touch keys The condition during calculation No key input is allowed and no data is displayed during calculation. a. b. Display method Set number and result of operation are displayed in the right margin, minus floating. Display of decimal number operation results. Display is made according to the display format that has been set by the F E key. * Floating mode 10 100 10 | x | 10 -99 10 | x | 10-9 0 and 10-9 | x | 1010 : Exponent display : Exponent display : Floating display * Engineering mode 0 and 10-99 | x | 10100 (all ranges); Exponent display. The F E key also converts the display format of a displayed numerical value simultaneously with the display format setting. At the same time, the number of digits below the decimal point of the above modes follows the display format assigned by the 2ndF and F E keys. Further, in the same manner as the F E key, the conversion is also takes place simultaneously with the display format setting. When the number of digits is specified, the last digit displayed is a rounded number, and when there is no specification of the number of digits, the last digit displayed is a cut number. 3 = % +M DC ATAD 2x M XPLC MR ) s X x n Y b yx TATS C/NO EC !n REWOP EF BAT ( + CED TCO XEH X NIB FFO 1- nat nat 2x x/1 a r DNR 3 9 6 C x3 gol F 01 1- soc soc x X -/+ 8 5 2 B E GRD GRD 1- nis nis nl xy X yx e PXE A GED D pyh pyhcra 7 0 1 4 Fdn2 IZ1242C Example: Negative numbers are not displayed with the minus symbol "-" but are displayed in hexadecimal, octal, and binary two's complements. d.

DEG RAD RAD GRAD GRAD DEG : RAD = DEG x /180 : GRAD = RAD x 200/ : DEG = GRAD x 0.9 3. 0 - 9 a. In setting data in the mantissa section, it is set at the right margin, and the data in more than 11 digits cannot be input. b. At the data input against the exponent, the last two numbers are efficients. 4. * RND 6 IZ1242C 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. + , - , x, /, =, ( ) 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) yx , xy 4) x, / 5) +, 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. (Key is accepted only immediately after CE, +, -, x, /, yx, xy, =, (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. 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. 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. Memory calculation ( x M, RM, M+ ) The memory register M used by these keys is a completely independent single memory. Display data is added to M (memory register) by M+ key. If data overflows at this time, the processing data is held. Display data is stored in M by x M key. Contents of M is displayed by MR key. When any data except for 0 is stored in M, the special display M illuminates. 6. a. b. c. d. e. 7. a. b. c. d. e. 8. a.
