remain
natural number
Returns the remainder of a division.
Example
• Obtain the remainder when
123 is divided by 5.
1 2 3 M B 0 5
E
CPROB
Use the PROB sub-menu items for probability calculations.
1 random random
[(number of trial)]
Returns a random decimal number between 0 and 1.
Example
• Make a list with three random
numbers.
Note: Set the “FSE” to “Fix” and “TAB”
to “0”.
@ { M C
1 | 100 , M C 1 | 100 ,
M C 1 | 100 @ } E
Note: The random functions (random, rndInt(, rndCoin, and rndDice)
will generate different numbers every time when the display is
redrawn. Therefore, the table values of the random functions will
be different every time. When in case of random-based graphing
calculations, the tracing values and other parameters of the graph
will not match the graph's visual representation.
2 rndInt( rndInt(
minimum value, maximum value [, number of trial]
)
Returns a specified number of random integers, between a
minimum and a maximum value.
Example
• Produce eight random integers, ranging between values of 1
and 6.
