(13) Trigonometric and arctrigonometric function / Hyperbolic and arc hyperbolic trigonometric function (1-variable) ([sin], [cos], [tan], [sin-1], [cos-1], [tan-1]). These function are calculated according to respective defined areas and accuracy shown in behind chart, any displayed result of operation can become operators. (14) Exponential and Logarithmic functions (1-variable). ([In], [Log], [eX], [10X]) Same as Trigonometric functions. (15) Reciprocal, Square, Square Root, and Cube Root. ([1/x] , [x2], [ (16) [ ], [ 3 ])same as Trigonometric functions. ] a. These keys convert degrees, minutes, seconds, into decimal degree and decimal degrees into degree minutes, and seconds. " format, the integer part of display data is b. On the " regarded as degree, 2 digits below the decimal point as minutes and the 3rd digit and belows as seconds. Example: [ ] <degree minute second> ] 2 06 3999 2. 111111111 [SHIFT] [ (39. 99 seconds) BIN (17) Binary mode ([SHIFT], [ ], [0], [1] ). a. Data input and output are both binary integers in a maximum of 10 digits. A negative number is expressed in binary of two's complement. - E5 - SR8D1A-E. RTF SIZE : 140x75mm SCALE 2:1 2003/8/22 c. The range of internal operation is as shown below and if the result of the operation exceed the range, it becomes an error (overflow).

Parenthesis are used when it is desired to perform calculations in a first priority that usually followed for the +, -, x, ÷, xy, y x , operations. In other words the "(" ")" force those prior operations it to be pending until the calculation inside the parenthesis are performed. 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. [. . . ]
