Definable memories (D1-D4) You can store functions or operations in definable memories (D1-D4). • To store a function or operation, press x, followed by a definable memory key (I, J, K, or L), followed by the operation you want to store. Menu-related operations, such as @ J, cannot be stored. Press j to return to the previous display. • To call a stored function or operation, press the corresponding memory key. Calling a stored function will not work if the function that is called would be unusable in the current context. • Any functions or operations that are stored in a definable memory will be replaced when you save a new one into that memory. • You cannot store functions or operations in definable memories when entering values or items in STAT, MATRIX, LIST, or EQUATION modes, or into solver functions or simulation calculations. Chain Calculations 11 The previous calculation result can be used in the subsequent calculation. However, it cannot be recalled after entering multiple instructions or when the calculation result is in matrix/list format. Fraction Calculations 12 Arithmetic operations and memory calculations can be performed using fractions. In NORMAL mode, conversion between a decimal number and a fraction can be performed by pressing U. Notes: • Improper/proper fractions will be converted to and displayed as decimal numbers if the number of digits used in their expression is greater than nine. In the case of mixed fractions, the maximum number of displayable digits (including integers) is eight. • To convert a sexagesimal value to a fraction, first convert it by pressing @ :. Binary, Pental, Octal, Decimal, and Hexadecimal Operations (N-base) 13 Conversions can be performed between N-base numbers in NORMAL mode. The four basic arithmetic operations, calculations with parentheses, and memory calculations can also be performed, along with the logical operations AND, OR, NOT, NEG, XOR, and XNOR on binary, pental, octal, and hexadecimal numbers. Conversion to each system is performed with the following keys: @ z ("BIN" appears), @ r ("PEN" appears), @ g ("OCT" appears), @ h ("HEX" appears), @ / ("BIN", "PEN", "OCT", and "HEX" disappear) Note: The hexadecimal numbers A-F are entered by pressing A B C D E F K, m, A, l, i, and H. In the binary, pental, octal, and hexadecimal systems, fractional parts cannot be entered. When a decimal number having a fractional part is converted into a binary, pental, octal, or hexadecimal number, the fractional part will be truncated. Likewise, when the result of a binary, pental, octal, or hexadecimal calculation includes a fractional part, the fractional part will be truncated. In the binary, pental, octal, and hexadecimal systems, negative numbers are displayed as a complement. Time, Decimal, and Sexagesimal Calculations 14 You can convert between decimal and sexagesimal numbers, and from sexagesimal numbers to seconds or minutes. In addition, the four basic arithmetic operations and memory calculations can be performed using the sexagesimal system. Notation for sexagesimal is as follows: Degree Minute Second Coordinate Conversions 15 • Before performing a calculation, select the angular unit. • The calculation result is automatically stored in the X and Y memories (r or x in X memory, and θ or y in Y memory). • The results of coordinate conversions will be displayed as decimal numbers even in the WriteView editor. Rectangular coord. Polar coord. Physical Constants and Metric Conversions 16 Calculations using physical constants To recall a constant, press K, then select a physical constant from the list. (Each item is labeled with a 2-digit number.) • To scroll up or down the list of constants, press u (l) or d (r). Use @ u (l) or @ d (r) to jump to the first or last page. • Enter the first digit of the 2-digit item number to jump to the page containing the number that begins with that digit. • When you enter the second digit, the constant is displayed automatically according to the display and decimal placement settings. • Physical constants can be recalled in NORMAL (excluding N-base), STAT, CPLX, MATRIX, LIST, and EQUATION modes. • The following table lists the physical constants. See the calculation example sheet for physical constant symbols and units. Note: Physical constants and metric conversions are based on the 2006 CODATA recommended values, or on the 1995 Edition of the "Guide for the Use of the International System of Units (SI)" released by NIST (National Institute of Standards and Technology).

See the calculation example sheet for the metric conversion reference table.
