12. Exponential and logarithmic functions
(ex 10x In log)
Same as trigonometric functions
13. Reciprocal, square, square root and cube root.
(1/x x2
,3 )
Same as trigonometric function
14. Factorial function (n!)
n! = n×(n-1)×(n-2)×⋅⋅⋅⋅⋅⋅×2×1
Same as trigonometric
15. → DEG → DMS
a. These keys convert degrees, minutes and seconds into decimal degrees and decimal degrees into degree
minutes and seconds.
b. On the DMS format, the integer part of display data is regarded as degrees, 2 digits below the decimal point
as minutes and the 3rd digit and below as seconds.

16. Coordinate conversion (a b→rθ→xy)
a. These keys convert the rectangular coordinates into the polar coordinates into the rectangular coordinates.
The angle units that have been set by the DRG key follows.
b. Respective defined areas and accruacy are as shown in (6), however, the range of θ obtained by R→P in
degree is as follows:

c. Input of 2 variables is performed by setting.
x or r by pressing a key and
y or θ by pressing b key.
d. The operation result of x or R is obtained in the display register of by pressing a key and y or θ by pressing b
key.
