"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
Generate random numbers
between 0 and 1.
Generate random integers
between 1 and 6.
"randLi t" Function
Syntax: randList( n [, a, b])
Function:
• Omitting arguments "a" and "b" returns a list of
values.
• Specifying arguments "a" and "b" returns a list of
values in the range of "a" through "b".
De cription:
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
Generate a list of three
elements that contain
decimal random values.
Generate a list of five
elements that contain
random values in the range
of 1 through 6.
"randNorm" Function
The "randNorm" function generates a 10-digit normal random number based on a specified
mean σ and standard deviation μ values.
Syntax: randNorm( σ , μ [, n ])
Function:
• Omitting a value for " n " (or specifying 1 for " n ") returns the generated random number as-is.
• Specifying a value for " n " returns the specified number of random values in list format.
