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 | Quadrant | 0°≤θ≤ 90° |
2nd | Quadrant | 90°≤θ≤ 180° |
3rd | Quadrant | |
4th | Quadrant |
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.
