b
formula is: ( f(x)) = f(a) ⋅ f(a+1) ⋅ f(a+2) ⋅ ... ⋅ f(b). The Natural Display
x=a b
input syntax is ( f(x)), while the Linear Display input syntax is (f(x), a,
x=a
b). a and b are integers in the range of a 1 ⋅ 1010, b 1 ⋅ 1010, a b. See

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

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 
17.
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 
18.
GCD, LCM: GCD determines the greatest common divisor of two values, while LCM determines the least common multiple. See
