For commutative operations such as and , the order of the operands does not affect the calculated result. If you mistakenly enter the operand for a noncommutative two argument operation in the wrong order in RPN mode, simply press the key to exchange the contents in the x- and y-registers. This is explained in detail in Chapter 2 (see the section entitled Exchanging the X- and Y-

Registers in the Stack).

Controlling the Display Format

All numbers are stored with 12-digit precision; however, you may control the number of digits used in the display of numbers via the options in the Display menu. Press 8to access this menu. The first four options (FIX, SCI, ENG, and ALL) control the number of digits in the display of numbers. During some complicated internal calculations, the calculator uses 15–digit precision for intermediate results. The displayed number is rounded according to the display format.

Fixed–Decimal Format ()

FIX format displays a number with up to 11 decimal places (11 digits to the right of the "" or "" radix mark) if they fit. After the prompt _, type in the number of decimal places to be displayed. For 10 or 11 places, press or .

For example, in the number , the "7", "0", "8", and "9" are the decimal digits you see when the calculator is set to FIX 4 display mode.

Any number that is too large (1011) or too small (10-11) to display in the current decimal–place setting will automatically be displayed in scientific format.
