21. Static calculation mode (2ndF, STAT)

a. Pressing these keys shall set the static calculation mode.

b. The available number of data is a positive integer, such as 0≤n≤9999999999,and when the number of data

exceeds this integer, it becomes an error.

c. The input range of the data is as follows: 0≤data≤1x1050

This data exceeds the ranges, it becomes an error.
