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.
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 (3.14592654) of a 12-digit value (3.1459265359) according to the set display
format.
b. A value that is used in a subsequent operation is the above the 12-digit value.
c. The display is cleared by the following 1st numeric key and new data is set.
9. % Calculation

10. Trigonometric and arctrigonometric functions (1 Variable)
(sin cos tan sin-1 cos–1 tan-1)
These functions are calculated according to respective defined areas and accuracy show in (6), and displayed
result of operation can become operators.
11. Hyperbolic and archyperbolic function
(hyp→sin cos tan, archyp→sin cos tan)
Same as trigonometric function.
