The FIX setting affects all decimal results and the mantissa of Scientific and Engineering notation results. The TI-30X ÙS automatically rounds the result to the number of decimal places selected. For example, when the decimal is set to 2 places, 0. 147 becomes 0. 15 when you press <. The TI-30X ÙS also rounds or pads resulting values with trailing zeros to fit the selected setting. For example, when the decimal is set to 5 places, 0. 147 becomes 0. 14700 when you press <. All results are displayed to the FIX setting until you clear the setting by either pressing % ‚ 8 or selecting F(floating) on the decimal notation menu.
