CMPLX ........................................................... F 2 • The current angle unit setting (Deg, Rad, Gr a) affects CMPLX Mode calculations.
E-8 Imaginary axis Real axis k Absolute V alue and Argument Calculation Supposing the imaginary number expressed by the rectangular form z = a + bi is represented as a point in the Gaussian plane, you can determine the absolute value ( r ) and argument ( ) of the comple x number .
E-9 B ASE •Y ou select rectangular f or m ( a + bi ) or polar f or m ( r ⬔ ) for display of complex number calculation results. F ... 1 (Disp) r 1 ( a + bi ): Rectangular form 2 ( r ⬔ ):.
E-10 •Y ou can use the f ollowing 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.

E-12 COMP Differ ential Calculations The procedure described below obtains the derivative of a function. Use the F key to enter the COMP Mode when you w ant to perf or m a calculation inv olving differentials . COMP ...................................
E-13 COMP •Y ou can omit input of ∆ x , if y ou want. The calculator automatically substitutes an appropriate value for ∆ x if you do not input one. •D iscontinuous points and extreme changes in the value of x can cause inaccurate results and errors.
E-14 Power Supply The type of battery you should use depends on the model n umber of y our calculator . fx-115MS The TW O W A Y PO WER system actually has two power supplies: a solar cell and a G13 T ype (LR44) button battery . Normally , calculators equipped with a solar cell alone can operate only when relativ ely bright light is present.
E-15 fx-100MS This calculator is powered b y a single AA-size battery . •R eplacing the Battery Dim figures on the displa y of the calculator indicate that battery power is low . Continued use of the calculator when the battery is low can result in improper operation.
E-16 Specifications Po wer Supply: fx-100MS: Single AA-size battery (R6P(SUM-3)) fx-115MS: Solar cell and a single G13 T ype button battery (LR44) Battery Life: fx-100MS: Approximately 17,000 hours contin uous display of flashing cursor . Appro ximately 2 years when left with power tur ned off.
