u Random Extraction of List Data Elements (RanSamp#)
This function randomly extracts elements from list data and returns the results in list format.
RanSamp# (List X,
n [,m])
List X ... Any list data (List 1 to List 26, Ans, {list format data}, sub-name)
n ... Number of tries (When m = 1, the number of elements is 1 < n < List X. When m = 0,
1 <
n < 999.)
m ... m = 1 or 0 (When m = 1, each element is extracted only once. When m = 0, each
element can be extracted multiple times.)
•
m = 0 is used when the m setting is omitted.
Example Operation
List 1 = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
RanSamp# (List 1, 3, 1)
(Randomly extracts three elements from
List 1 and displays the result on the ListAns
screen.)

!b(List)b,3,1)w
List 2 = {1, 3, 6, 7}
RanSamp# (List 2, 10)
(Randomly extracts 10 elements from List
2 and displays the result on the ListAns
screen. Elements are extracted repeatedly.)

• With polar coordinates,  can be calculated and displayed within a range of
–180°<  < 180° (radians and grads have same range).
• Be sure to specify Comp for Mode in the Setup screen.
