Specify the angle unit before
performing calculations.
The calculation result for
r and θ
and for
x and y are each assigned
respectively to variables X and Y.
Calculation result
Q
is displayed
in the range of −180°
Q
180°.
x ! : Factorial function. See
9
.
Abs : Absolute value function. Note that the input method is different
depending upon whether you are using Natural Display or Linear Display.
See
10
.
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
11
.
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
12
.
Function Calculations
For actual operations using each function, see the “Examples” section
following the list below.
: P is displayed as 3.141592654, but P = 3.14159265358980 is used for
internal calculations.
e : e is displayed as 2.718281828, but e = 2.71828182845904 is used for
internal calculations.

: Hyperbolic functions. Input a
function from the menu that appears when you press E. The angle unit
setting does not affect calculations. See

°,
r
,
g
: These functions specify the angle unit. ° specifies degrees,
r
radians,
and
g
grads. Input a function from the menu that appears when you perform
the following key operation: (DRG). See

,
: Exponential functions. Note that the input method is different
depending upon whether you are using Natural Display or Linear Display.
See

.
log
: Logarithmic function. Use the : key to input log
a
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
5
.
ln
: Natural logarithm to base e. See
