[. . . ] Pressing this key after [SHIFT] key shall change the mode of angle and shall convert the displayed data. DEG RAD : RAD = DEG x /180 RAD GRAD : GRAD = RAD x 200/ GRAD DEG : DEG = GRAD x 180/200 (6) [0] ~ [9] : Press these keys in their logical sequence to enter numbers. [. . . ] When any arithmetic functions constant mode has been set, the displayed number is converted from a percentage to a decimal. When [=] key is pressed after [%] following arithmetic function will be executed. These function are calculated according to respective defined areas and accuracy shown in behind chart, any displayed result of operation can become operators. These keys convert degrees, minutes, seconds, into decimal degree and decimal degrees into degree minutes, and seconds. Data input and output are both octal integers with a maximum of 10 digits. A negative number is expressed in the octal number display of two's complement. Data input and output are both hexadecimal integer with a maximum of 10 digits. A negative number is expressed in a hexadecimal number of two's complement. Used to exchange the displayed number with the contents of an internal register. These keys convert the rectangular coordinate into the polar coordinate and the polar coordinate into the rectangular coordinate. Respective defined areas and accuracy are as shown in behind chart however, the range of obtained by RP in degree is as follows: 1st 2nd 3rd 4th Quadrant Quadrant Quadrant Quadrant 0° 90° 90° 180° ­180°­90° ­90° 0° When you calculate the calculation of statistics, pressing [SHIFT] [ ON/C ] keys for statistics mode ("SD" sign ). When you clear to statistics mode, press the same keys ([SHIFT] You can't perform the memory calculation, parenthesis calculation or conversion of coordinates. [. . . ] Parenthesis may be used in a chained calculation as long as the total of levels ending due to the automatic priority Logic and parenthesis does not exceed 15.
