Resumen del manual
The result is rounded to a 10-digit mantissa before it is displayed. • For mixed arithmetic calculations, multiplication and division are given priority over addition and subtraction. Example Operation 23 + 4.5 - 53 = -25.5 23Ш 4.5R53 W 56 x (-12) + (-2.5) = 268.8 56* —12/ —2.5W (2 + 3) x 102 = 500 (2Ш3)® 1E2W*1 1 + 2 - 3 x 4 + 5 + 6 = 6.6 1ffl2R3*4S5ffl6W 100 - (2 + 3) x 4 = 80 100R(2ffl3m®4W 2 + 3 x (4 + 5) = 29 2ffl3®m4ffl5W*2 (7 - 2) x (8 + 5) = 65 m7R2mm8ffl5mw*3 = 0.3 4 x 5 6 sm4*5mw*4 (1 + 2i) + (2 + 3i) = 3 + 5i msffic s awmfflmdffl dsawmw 5 II - (2 x + (2 mc+s a(i)msmcR s aw mw *1 ( 2 + 3 ) E 2 does not produce the correct result. Be sure to enter this calculation as shown. *2Final closed parentheses (immediately before operation of the W key) may be omitted, no matter how many are required. 3A multiplication sign immediately before an open parenthesis may be omitted. 4This is identical to 6 / 4 / 5 W. 19990401 2-1-2 Basic Calculations ■ Number of Decimal Places, Number of Significant Digits, Normal Display Range [SET UP]-»»ngflCTlI-[Fix] / [Sci] / [Norm] • Even after you specify the number of decimal places or the number of significant digits, internal calculations are still performed using a 15-digit mantissa, and displayed values are stored with a 10-digit mantissa. Use Rnd of the Numeric Calculation Menu (NUM) (page 2-4-1) to round the displayed value off to the number of decimal place and number of significant digit settings. • Number of decimal place (Fix) and number of significant digit (Sci) settings normally remain in effect until you change them or until you change the normal display range (Norm) setting. • • • • • Example 100 + 6 = 16.66666666...
