Relational operator =, G, >, <, ≥, ≤ @ And, and # Or, or, xor, xnor • When functions with the same priority are used in series, execution is performed from right to left. exIn 120 → ex {In( 120 )} Otherwise, execution is from left to right. • Anything contained within parentheses receives highest priority. Example 2 + 3 × (log sin2π 2 + 6.8) = 22.
PAGE 7
Before Starting Calculations... 1-1 k Stacks The unit employs memory blocks, called stacks, for storage of low priority values and commands. There is a 10-level numeric value stack, a 26-level command stack, and a 10-level program subroutine stack. If you execute a formula so complex it exceeds the amount of stack space available, an error message appears on the display (Stk ERROR during calculations or Ne ERROR during execution of a program subroutine).
PAGE 8
1-1 Before Starting Calculations... k Overflow and Errors Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display. Further operation of the calculator is impossible while an error message is displayed. The following events cause an error message to appear on the display. • When any result, whether intermediate or final, or any value in memory exceeds ±9.999999999 × 1099 (Ma ERROR). P.

Before Starting Calculations... 1-1 k Graphic Display and Text Display The unit uses both a graphic display and a text display. The graphic display is used for graphics, while the text display is used for calculations and instructions. The contents of each type of display are stored in independent memory areas. u To switch between the graphic display and text display Press !6(G↔T). You should also note that the key operations used to clear each type of display are different.

1-2 Memory k Variables This calculator comes with 28 variables as standard. You can use variables to store values to be used inside of calculations. Variables are identified by single-letter names, which are made up of the 26 letters of the alphabet, plus r and θ . The maximum size of values that you can assign to variables is 15 digits for the mantissa and 2 digits for the exponent. Variable contents are retained even when you switch power off.

1-2 Memory Example To assign a value of 10 to variables A through F Abaa!aA 3(~)Fw k Function Memory P.31 Function memory is convenient for temporary storage of often-used expressions. For longer term storage, we recommend that you use the GRAPH Mode for expressions and the PRGM Mode for programs. u To display the Function Memory Menu K6(g)6(g)3(FMEM) 1(STO) ........

1-2 Memory u To use stored functions Once you store a function in memory, you can recall it and use it for a calculation. This feature is very useful for quick and easy input of functions when programming or graphing. Example To store x3 + 1, x2 + x into function memory, and then graph: y = x3 + x2 + x + 1 Use the following View Window parameters.

1-2 Memory k Clearing Memory Contents You have a choice of two differenct procedures that you can use to clear memory contents. • Clearing specific data within a selected data type • Clearing all data within a specific data type u To clear specific data within a selected data type 1. In the memory status screen, use f and c to move the highlighting to the data type you want to clear. 2. Press 1 (DEL).
