(21) [X ↔ Y] : Exchange key.
Used to exchange the displayed number with the contents of an
internal register.
(22) [a], [b], [R → P], [P → R] : Coordinate conversion.
a. These keys convert the rectangular coordinate into the polar
coordinate and the polar coordinate into the rectangular
coordinate. The range units that have been set by the [DRG]
key follow.
b. Respective defined areas and accuracy are as shown in
behind chart however, the range of θ obtained by R → P in
degree is as follows:
1st
2nd
3rd
4th
c. Input of 2 variable is performed by setting x or r pressing [a]
key and y or θ pressing [b] key.
d. The operation result of x or r is obtained in the display register
or by pressing [a] key and y or θ by pressing [b] key.
