F 1 k Inputting Engineering Symbols COMP EQN CMPLX · Turning on engineering symbols makes it possible for you to use engineering symbols inside your calculations. E-6 · To turn engineering symbols on and off, press the F key a number of times until you reach the setup screen shown below. Disp 1 · Press 1. On the engineering symbol setting screen that appears, press the number key ( 1 or 2) that corresponds to the setting you want to use. 1(Eng ON): Engineering symbols on (indicated by "Eng" on the display) 2(Eng OFF): Engineering symbols off (no "Eng" indicator) · The following are the nine symbols that can be used when engineering symbols are turned on. To input this symbol: Perform this key operation: Ak k (kilo) M (Mega) AM G (Giga) Ag T (Tera) At m (milli) Am µ (micro) AN n (nano) An p (pico) Ap f (femto) Af Unit 103 106 109 1012 10­3 10­6 10­9 10­12 10­15 · For displayed values, the calculator selects the engineering symbol that makes the numeric part of the value fall within the range of 1 to 1000. · Engineering symbols cannot be used when inputting fractions. · Example: 9 Ö10 = 0. 9 m (milli) Eng F . . . . . You cannot input values that include decimal part and an exponent. · If you input a value that includes a decimal part, the unit automatically cuts off the decimal part. · Negative binary, octal, and hexadecimal values are produced by taking the two's complement. E-10 · You can use the following logical operators between values in Base-n calculations: and (logical product), or (logical sum), xor (exclusive or), xnor (exclusive nor), Not (bitwise complement), and Neg (negation). · The following are the allowable ranges for each of the available number systems. 1000000000 0 Octal 4000000000 0 Decimal ­2147483648 Hexadecimal 80000000 0 Binary x x x x x x x 1111111111 0111111111 7777777777 3777777777 2147483647 FFFFFFFF 7FFFFFFF · Example 1: To perform the following calculation and produce a binary result: 101112 110102 1100012 Binary mode: tb 10111 + 11010 = 0. b · Example 2: To perform the following calculation and produce an octal result: 76548 ÷ 1210 5168 Octal mode: to 0. o l l l 4 (o) 7654 \ l l l 1 (d) 12 = · Example 3: To perform the following calculation and produce a hexadecimal and a decimal result: 12016 or 11012 12d16 30110 Hexadecimal mode: th 0.
