Rectangular Polar Coordinates
Coordinates (Rec) (Pel)
•Coordinate conversion can be performed in the
COMP and STAT calculation modes.
Converting to Polar Coordinates (Pol)
Pol(X,Y) X: Specifies the rectangular coordinate
X value
Y: Specifies the rectangular coordinate
Y value
• Calculation result 6 is displayed in the range of
-180°< 0 ^180°
•Calculation result 9 is displayed using the
calculator's default angle unit.
• Calculation result r is assigned to variable X,
while y is assigned to Y.
Converting to Rectangular Coordinates (Rec)
Rec(r, 0 ) r: Specifies rvalue of polar coordinate
9 : Specifies 9 value of polar coordinate
• Input value 0 is treated as an angle value, in
accordance with the calculator's default angle unit
setting.
• Calculation result x is assigned to variable X, while
9 is assigned to Y.
• If you perform coordinate conversion inside of an
expression instead of a stand-alone operation,
the calculation is performed using only the first
value (either the r-value or the X-value) produced by
the conversion.
Example: Pol(V2, V2)-i-5=2-i-5=7

Absolute Value Calculation (Abs)
When you are performing a real number calculation,
this function simply obtains the absolute value.
Example: Abs{2—7)=5

Random Number (Ran#)
This function generates a 3-digit pseudo random
number that is less than 1.

3 digit decimal values are converted to 3-digit intergei
values by multiplying bylOOO.
Note that values shown here are examples only.Values
actually generated by your calculator will be different.
Permutation (nPr) and Combination (nCr)
These functions make it possible to perform
permutation and combination calculations,
n and rmust be integers in the range of
0^/How many four-person permutations and combinations
are possible for a group of 10 people?

Rounding Function (Rnd)
This function rounds the value or the result of the
expression in the function's argument to the number
of significant digits specified by the number of
display digits setting.
Display Digits Setting: Normi or Norm2
The mantissa is rounded to 10 digits.
Display Digits Setting: Fix or Sci
The value is rounded to the specified number of
digits.
