log

: Logarithmic function. Use the l key to input log

b as log ( a , b ). Base

10 is the default setting if you do not input anything for

a . The & key also

can be used for input, but only while Natural Display is selected. In this

case, you must input a value for the base. See

: Natural logarithm to base e . See

, x

, x ^, ), #, ", x

−1

: Powers, power roots, and reciprocals. Note

that the input methods for

x ^, ), #, and " are different depending upon

whether you are using Natural Display or Linear Display. See

Note: The following functions cannot be input in consecutive sequence:

, x^, x

−1

. If you input 2ww, for example, the final w will be ignored. To

input

, input 2w, press the d key, and then press w(B).

Pol, Rec : Pol converts rectangular coordinates to polar coordinates, while

Rec converts polar coordinates to rectangular coordinates. See

Pol(

x , y ) = ( r ,  ) Rec( r ,  ) = ( x , y )

Rectangular Polar

Coordinates (Rec) Coordinates (Pol)

Specify the angle unit before

performing calculations.

The calculation result for

r and 

and for

x and y are each assigned

respectively to variables X and Y.

Calculation result

is displayed

in the range of −180° 



180°.

x ! : Factorial function. See

Abs : Absolute value function. Note that the input method is different

depending upon whether you are using Natural Display or Linear Display.

See

Ran# : Generates a 3-digit pseudo random number that is less than 1. The

result is displayed as a fraction when Natural Display is selected. See

RanInt# : For input of the function of the form RanInt#(

a, b), which generates

a random integer within the range of

a to b. See

nPr, nCr : Permutation (nPr) and combination (nCr) functions. See

Rnd : The argument of this function is made a decimal value and then rounded

in accordance with the current number of display digits setting (Norm, Fix, or

Sci). With Norm 1 or Norm 2, the argument is rounded off to 10 digits. With

Fix and Sci, the argument is rounded off to the specified digit. When Fix 3

is the display digits setting, for example, the result of 10 ÷ 3 is displayed

as 3.333, while the calculator maintains a value of 3.33333333333333 (15

digits) internally for calculation. In the case of Rnd(10÷3) = 3.333 (with Fix

3), both the displayed value and the calculator’s internal value become

3.333. Because of this a series of calculations will produce different results

depending on whether Rnd is used (Rnd(10÷3) × 3 = 9.999) or not used (10

÷ 3 × 3 = 10.000). See

Note: Using functions can slow down a calculation, which may delay display

of the result. Do not perform any subsequent operation while waiting for the

calculation result to appear. To interrupt an ongoing calculation before its

result appears, press A.
