When operations performed these keys according numerical expression, result operation obtained according mathematical priorities, priorities discriminated are: Variable function Expression (The most inner expression priority case multiple parentheses) Whenever operated, calculator discriminates above priorities holds data operation keys pending required. This pending action possible times more pending become error. (Key accepted only immediately after (keys accepted other cases. When this accepted, displayed data cleared When first accepted, special display illuminates. When parenthesis expression completed keys when cleared ON/C key, etc, when errors generated, special display goes out. within allowable range pending. input into place expression many times desired. However, pressed continuously times more, comes error. From viewpoint numerical expression, even when corresponding pressed, operation executed pressed. other hand, when pressed pressed without pressing corresponding key, operation also completed according priority. Memory calculation memory register used these keys completely independent single memory. Display data added (memory register) key. data overflows this time, processing data held. Display data stored key. Contents displayed key. When data except stored special display illuminates. This displays rounded value (3.141592654) 12-digit value (3.14159265359) according display format. value that used subsequent operation above 12-digit value.
