-1 Basic Calculations k Arithmetic Calculations • Enter arithmetic calculations as they are written, from left to right. • Use the - key to input the minus sign before a negative value. • Calculations are performed internally with a 15-digit mantissa. The result is rounded to a 10-digit mantissa before it is displayed. • For mixed arithmetic calculations, multiplication and division are given priority over addition and subtraction. Example Operation 23 + 4.5 – 53 = –25.5 Display 23+4.5-53w –25.
Basic Calculations P.53 2-1 • Even after you specify the number of decimal places or the number of significant digits, internal calculations are still performed using a 15-digit mantissa, and displayed values are stored with a 10-digit mantissa. Use Rnd (4) of the Numeric Calculation Menu (NUM) to round the displayed value off to the number of decimal place and number of significant digit settings.
2-1 Basic Calculations • If the same calculation is performed using the specified number of digits: 200/7w The value stored internally is cut off to the number of decimal places you specify. 28.571 K6(g) 4(NUM)4(Rnd)w * Ans × _ 14w 28.571 399.994 k Calculations Using Variables Example 48 Operation Display 193.2aaAw 193.2 193.2 ÷ 23 = 8.4 aA/23w 8.4 193.2 ÷ 28 = 6.9 aA/28w 6.
2-2 Special Functions k Answer Function The unit’s Answer Function automatically stores the last result you calculated by pressing w(unless the wkey operation results in an error). The result is stored in the answer memory.
2-2 Special Functions k Using the Replay Function The Replay Function automatically stores the last calculation performed into replay memory. You can recall the contents of the replay memory by pressing d or e. If you press e, the calculation appears with the cursor at the beginning. Pressing d causes the calculation to appear with the cursor at the end. You can make changes in the calculation as you wish and then execute it again. Example To perform the following two calculations 4.12 × 6.4 = 26.368 4.
Special Functions 2-2 Make necessary changes. d![b Execute it again. w k Using Multistatements Multistatements are formed by connecting a number of individual statements for sequential execution. You can use multistatements in manual calculations and in programmed calculations. There are two different ways that you can use to connect statements to form multistatements. • Colon (:) Statements that are connected with colons are executed from left to right, without stopping.
2-3 Function Calculations k Function Menus This calculator includes five function menus that give you access to scientific functions that are not printed on the key panel. • The contents of the function menu differ according to the mode you entered from the Main Menu before you pressed the K key. The following examples show function menus that appear in the RUN or PRGM Mode. uHyperbolic Calculations (HYP) K6(g)2(HYP) 1 2 3 4 5 6 1 (sinh) ........ Hyperbolic sine 2 (cosh) .......

Function Calculations 2-3 k Angle Units P.53 • Once you specify an angle unit, it remains in effect until you specify a different one. The specification is retained even if you switch power off. P.5 • Be sure to specify “Comp” for Calculation/Binary, Octal, Decimal, Hexadecimal Setting Mode. Example Operation To convert 4.25 rad to degrees: !Zcccc 1(Deg)J4.25K6(g) 5(ANGL)2(r)w 243.5070629 47.3+82.52(r)w 4774.20181 47.3° + 82.5rad = 4774.
