SS($), SB(%), !, 0, 1!(#), ® Displaying Calculation Results in a Form that Includes ', n, etc. (Irrational Number Form) When “MthIO” is selected for the input/output format, you can specify whether calculation results should be displayed in a form that includes expressions like 'and n (irrational number form). • Pressing = after inputting a calculation displays the result using irrational number form. • Pressing d = after inputting a calculation displays the result using decimal values. Note • When “LinelO” is selected for the input/output format, calculation results are always displayed using decimal values (no irrational number form) regardless of whether you press = or d =. • n form (form that includes n within irrational number display) display conditions are the same as those for S-D conversion. For details, see “Using S-D Transformation”. Example 1: ' +' = 3' MATH 2 E-16 ' Example 2: sin (60) = — I MATH (Angle Unit: Deg) Example 3: sin-1 (0.5) = — n I MATH (Angle Unit: Rad) HS(sin-1)0R5H sin-K0.5 Math • The following are the calculations for which ' form (form that includes ' within irrational number display) results can be displayed. a.Arithmetic calculations of values with square root symbol ('), x2, x3, x-1 b. Trigonometric function calculations The following are the input value ranges for which ' form is always used for display of trigonometric calculation results. Angle Unit Setting Angle Value Input Input Value Range for ' Form Calculation Result Deg Units of 15° |x| < 9 x 109 Rad Multiples of n radians |x| < 20n Gra Multiples of f grads |x| < 10000 Calculation results may be displayed in decimal form for input values outside of the above ranges. ■ ' Form Calculation Range Results that include square root symbols can have up to two terms (an integer term is also counted as a term). ' form calculation results use display formats like those shown below. ± a', ± d ± a', ± *" ± c f The following shows the range for each of the coefficients (a, b, c, d, e, f). 1 < a < 100, 1 < b < 1000, 1 < c < 100 0 < d < 100, 0 < e < 1000, 1 < f < 100 E-17 Example: 2' x 4 = 8' ' form 35 V2 x 3 = 148.492424 (= 105') decimal form 150' —5 = 8.485281374 2 x (3 - 2' ) = 6 - 4' ' form 23 x (5 - 2' ) = 35.32566285 (= 115- 46') decimal form 10' + 15 x 3' = 45' + 10' ' form 15 x (10' + 3' ) = 290.0743207 (= 45' + 150' ) decimal form ' + ' + '= ' + 3' ' form ' + ' + '= 5.595754113 decimal form The underlined areas in the above examples indicate what caused decimal form to be used. Reasons why the results of the examples are displayed in decimal form - Value outside of the allowable range - More than two terms in the calculation result • Calculation results displayed in ' form are reduced to a common denominator. a' + d' ^ a' + d' c f c’ • c' is the least common multiple of c and f. • Since calculation results are reduced to a common denominator, they are displayed in ' form even if coefficients (a' , c', and d) are outside the corresponding ranges of coefficients (a, c, and d). ' ' 10'+ 11' Example: 11 +10=—ÏÏ0— • The result is displayed in decimal form even when any intermediate result has three or more terms. Example: (1 + ' + ')(1 - '- ')(= -4 - 2') = -8.898979486 •If a term is encountered during the calculation cannot be displayed as a root (' ) form or a fraction, the calculation result is displayed in decimal form. Example: log3 + ' = 1.891334817 E-18 Basic Calculations (comp) This section explains how to perform arithmetic, fraction, percent, and sexagesimal calculations. All calculations in this section are performed in the COMP Mode (§ffl). ■ Arithmetic Calculations Use the ffl, 0, *, and 0 keys to perform arithmetic calculations. Example: 7 x 8 - 4 x 5 = 36 | LINE | 0B0ESS0i •The calculator automatically judges the calculation priority sequence. For more information, see “Calculation Priority Sequence”. Number of Decimal Places and Number of Significant Digits You can specify a fixed number of decimal places and significant digits for the calculation result. Example: 1 - 6 = | LINE | Initial default setting (Norml) 3 decimal places (Fix3) 3 significant digits (Sci3) B.1666666667 CT FIX À " О SCI A • For more information, see “Specifying the Number of Display Digits”. Omitting a Final Closed Parenthesis You can omit any closed parenthesis ( )) immediately preceding operation of the = key at the end of a calculation. This is true only in the case of Linear format. E-19 Example: (2 + 3) x (4 - 1) = 15 I LINE I (SfflSŒIH (HBŒIS ■ Fraction Calculations How you should input fractions depends on the input/output format that is currently selected.
