k Function Menus
This calculator includes five function menus that give you access to scientific functions not
printed on the key panel.
• The contents of the function menu differ according to the mode you entered from the Main
Menu before you pressed the K key. The following examples show function menus that
appear in the RUN
•
MAT mode.

u Probability/Distribution Calculations (PROB) [OPTN]-[PROB]
•{x!} ... {press after inputting a value to obtain the factorial of the value.}
•{nPr}/{nCr} ... {permutation}/{combination}
•{Ran#}... {pseudo random number generation (0 to 1)}
•{P(}/{Q(}/{R(} ... normal distribution probability {P(t)}/{Q(t)}/{R(t)}
•{t(} ... {value of normalized variate t(x)}

u Numeric Calculations (NUM) [OPTN]-[NUM]
•{Abs} ... {select this item and input a value to obtain the absolute value of the value.}
•{Int}/{Frac} ... select the item and input a value to extract the {integer}/{fraction} part.
•{Rnd} ... {rounds off the value used for internal calculations to 10 significant digits
(to match the value in the Answer Memory), or to the number of decimal places (Fix)
and number of significant digits (Sci) specified by you.}
•{Intg} ... {select this item and input a value to obtain the largest integer that is not greater
than the value.}
•{RndFi} ... {rounds off the value used for internal calculations to specified digits (0~9)
(see page 2-1-3).}
