Normal, Sci, Eng Notation modes only affect the way an answer is displayed on the home screen. Numeric answers can be displayed with up to 10 digits and a two-digit exponent. You can enter a number in any format. Normal notation mode is the usual way we express numbers, with digits to the left and right of the decimal, as in 12345.67. Sci (scientific) notation mode expresses numbers in two parts. The significant digits display with one digit to the left of the decimal. The appropriate power of 10 displays to the right of E, as in 1.234567E4. Eng (engineering) notation mode is similar to scientific notation. However, the number can have one, two, or three digits before the decimal; and the power-of-10 exponent is a multiple of three, as in 12.34567E3. Note: If you select Normal notation, but the answer cannot display in 10 digits (or the absolute value is less than .001), the TI.83 expresses the answer in scientific notation. Float, 0123456789 Float (floating) decimal mode displays up to 10 digits, plus the sign and decimal. 0123456789 (fixed) decimal mode specifies the number of digits (0 through 9) to display to the right of the decimal. Place the cursor on the desired number of decimal digits, and then press Í. The decimal setting applies to Normal, Sci, and Eng notation modes. The decimal setting applies to these numbers: • An answer displayed on the home screen • Coordinates on a graph (Chapters 3, 4, 5, and 6) • The Tangent( DRAW instruction equation of the line, x, and dy/dx values (Chapter 8) • Results of CALCULATE operations (Chapters 3, 4, 5, and 6) • The regression equation stored after the execution of a regression model (Chapter 12) 1-10 Operating the TI-83
