u “rand” Function
• The “rand” function generates random numbers. If you do not specify an argument, “rand”
generates 10-digit decimal values 0 or greater and less than 1.
Specifying two integer values for the argument generates random numbers between them.
Problem
Use this keyboard:
Operation
mth abc cat 2D
Generate random numbers Func [rand] w
between 0 and 1.
Generate random integers Func [rand] 1 , 6 w
between 1 and 6.
u “randList” Function
Syntax: randList (n [, a, b])
Function:
• Omitting arguments “a” and “b” returns a list of n elements that contain decimal random
values.
•Specifying arguments “a” and “b” returns a list of n elements that contain integer random
values in the range of “a” through “b”.
Description:
•“n” must be a positive integer.
• The random numbers of each element are generated in accordance with “RandSeed”
specifications, as with the “rand” function.
Problem
Use this keyboard:
Operation
mth abc cat 2D
Generate a list of three Func [randList] 3 w
elements that contain
decimal random values.
Generate a list of five Func [randList] 5, 1, 6 w
elements that contain
random values in the range
