A separator symbol is displayed every three digits when the integer part of the mantissa has more than three digits. Before getting started... k Modes Before starting a calculation, you must first enter the correct mode as indicated in the table below. To perform this type of calculation: Perform this key operation: To enter this mode: Basic arithmetic calculations F 1 COMP Standard deviation F 2 SD Regression calculations F 3 REG •Pressing the F key more than once displays additional setup screens. Setup screens are described in the sections of this manual where they are actually used to change the calculator setup. •In this manual, the name of the mode you need to enter in order to perform the calculations being described is indicated in the main title of each section. Example: SDStatistical REGCalculations E-7 Note! •To return the calculation mode and setup to the initial defaults shown below, press A B 2(Mode) =. Calculation Mode: COMP Angle Unit: Deg Exponential Display Format: Norm 1 Fraction Display Format: ab/c Decimal Point Character: Dot • Mode indicators appear in the upper part of the display. •Be sure to check the current calculation mode (SD, REG, COMP) and angle unit setting (Deg, Rad, Gra) before beginning a calculation. k Input Capacity • The memory area used for calculation input can hold 79 “steps.” One step is taken up each time you press a number key or arithmetic operator key ( +, ,, -, \ ). A A or p key operation does not take up a step, so inputting A D, for example, takes up only one step. •You can input up to 79 steps for a single calculation. Whenever you input the 73rd step of any calculation, the cursor changes from “_” to “k” to let you know memory is running low. If you need to input more than 79 steps, you should divide your calculation into two or more parts. •Pressing the g key recalls the last result obtained, which you can use in a subsequent calculation. See “Answer Memory” for more information about using the g key. k Making Corrections During Input •Use e and r to move the cursor to the location you want. •Press [ to delete the number or function at the current cursor position. •Press A K to change to an insert cursor t. Inputting something while the insert cursor is on the display inserts the input at the insert cursor position. • Pressing A K, or = returns to the normal cursor from the insert cursor. E-8 k Replay Function • Every time you perform a calculation, the replay function stores the calculation formula and its result in replay memory. Pressing the [ key displays the formula and result of the calculation you last performed. Pressing [ again back steps sequentially (new-to-old) through past calculations. •Pressing the e or r key while a replay memory calculation is on the display changes to the editing screen. •Pressing the e or r key immediately after you finish a calculation displays the editing screen for that calculation. •Pressing t does not clear replay memory, so you can recall the last calculation even after you press t. •Replay memory capacity is 128 bytes for storage of both expressions and results. • Replay memory is cleared by any of the following actions. When you press the 5 key When you initialize modes and settings by pressing A B 2(or 3) = When you change from one calculation mode to another When you turn off the calculator. k Error Locator •Pressing r or ...
