Abs : Absolute value function. Note that the input method is different
depending upon whether you are using Natural Display or Linear Display.

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 random integer within the range of
n r n r
P , C : 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
GCD, LCM : GCD determines the greatest common divisor of two values,
while LCM determines the least common multiple. 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.
