User manual CITIZEN CX-146

[. . . ] However, whenever you input the 73rd digit of any calculation, the cursor changes from " _ " to " " to let you know memory is running low. If you still need to input more, you should divide your calculation into two or more parts. Result line It displays a result of up to 10 digits, as well as a decimal, a negative sign, a " x10 " indicator, and a 2-digits positive or negative exponent. Indicators The following indicators appear on the display to indicate you the current status of the calculator. [. . . ] To replace a character, make the character underlined by using [ ] or [ ] to move the cursor, and then enter a new entry to replace the character. To insert a character, move the cursor to the position of the character where you want to insert, it will be inserted in the front of the character after pressing [ 2nd ] [ INS ] and entering a new character. (Note) : The blinking cursor " " means the calculator is in insert mode On the contrary, the blinking cursor is displayed as "_" and it means the calculator is in overwrite mode. After execution is completed, pressing [ 2nd ] [ ] or [ 2nd ] [ ] key will display the operation from the beginning or the end. After execution is completed or during entering, you can press either [2nd ] [ ] or [2nd ] [ ] to display previous input steps and edit values or commands for subsequent execution. (Note) : The replay function isn't cleared even when [ ON/AC ] is pressed or power is turned off, so contents can be re called even after [ ON/AC ] is pressed. When a mathematically illegal calculation is performed, error position display function will tell you with the cursor where the error is. You can also clear an error by pressing [ ON/AC ] and then re-entered the values and expression from the beginning. (Note) : Besides pressing [ STO ] key to store a value, you can also assign values to memory variable M by [ M+ ] or [ M­ ]. memory variable · The calculator has nine memory variables for repeated use : A, B, C, D, E, F, M, X, Y. You can store a real number in any of the nine -E5- This calculator uses memory areas, called " stacks ", to temporarily store values (numeric stack) and commands (command stack ) according to their precedence during calculations. To round off those values to the specified number of decimal places, press [ 2nd ] [ RND ]. The calculator enables you to repeat the last operation executed by pressing [ = ] key for further calculation. Even if calculations are concluded with the [ = ] key, the result obtained can be used for further calculation. Once a numeric value or numeric expression is entered and [ = ] is pressed, the result is stored by this function. (Note) : Even if execution of a calculation results in an error, however, Answer memory retains its current value. The calculator can calculate common and natural logarithms and anti-logarithms using [ log ], [ ln ], [ 2nd ] [ 10 x ], and [ 2nd ] [ e x ]. (Note) :Values are automatically displayed in decimal forma whenever the total number of digits of a fractional values (integer + numerator + denominator + separator marks) exceeds 10. To enter a mixed number, enter the integer part, press [ a b/c ], enter the numerator, press [ a b/c ], and enter the denominator ; To enter an improper fraction, enter the numerator, press [ a b/c ], and enter the denominator. Calculations containing both fractions and decimals are calculated in decimal format. The relation among the three angle units is: 180 ° = rad = 200 grad Angle conversions ( See Example 23. (Note) :When using those keys, make sure the calculator is set for the angle unit you want. [. . . ] Calculates the number of possible combinations of n items taken r at a time. The calculator also provides reciprocal ( [ x ] ), square root ( [ ] ), cubic root ( [ ] ), universal root [ ], square ( [ x 2 ] ), cubic ( [ x 3 ] ) and exponentiation ( [ x y ] ) functions. Always make sure you clear statistical memory by [ 2nd ] [ Scl ] before preforming standard deviation calculation. Individual data can be input using [ DT ] ; To delete data you just input, please press [ 2nd ] [ CL ]. [. . . ]
