[. . . ] However, if the key is pressed continuously 16 times or more, it becomes error. From a viewpoint of numerical expression when the corresponding " ) " key is not pressed, the operation is not executed even if the " ( " key is pressed. On the other hand, When the " ( " key is pressed and the " = " key is the pressed without pressing the corresponding " ) " key, the operation is also completed according to the priority. (10) [X M], [MR], [M+] Memory calculation a. 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 proceeding data is hold. 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. This key display a rounded value : 3. 141592654. Data input and output are both octal integers with a maximum of 10 digits. A negative number is expressed in the octal number display of two's complement. The range of internal operation is as shown below and if the result of the operation exceed the range, it becomes an error (overflow).

[. . . ] When exponential portion is entered: Numberals in exponential ponential portion are shifted right and last digit is erased. At this point, 0 replaces the first digit in the exponential. 42 [SHIFT] [CPLX] : Setting and clearing of complex number mode are executed alternately. (25) [x ] Yx y : Power / Root key [Xy] : Press any number [X], [Xy], any number [y], and [=] to raise y to the x power. [SHIFT] [ y y x ] : Press any number [x] [SHIFT] [ x ], any number [y], and [=] to display the y root x. DISPLAY · Display style - E10 - SR8D1A-E.
