Function Calculations

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.

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.
