RND
Function
RaNDom
• Generates random numbers.
RND(<numeric expression>)
Syntax
numeric expression • • • • The generated random number varies depending on
whether a positive, 0, or negative number is
specified.
Examples
A=RND(1) • • • • Assigns the value generated by RND(1) to the
variable A.
B=RND(0) • • • • Generates a random number of the sequence
generated previously and assign it to the variable B.
C=RND(-1) • • • • Generates a random number of a new random
number sequence and assign it to the variable C.
Description
• The RND function generates a random number in the interval from 0 and up to, but not
including, 1.
• The generated random number varies depending on the value specified in <numeric
expression>.
If <numeric expression> is positive • • • • A new random number is generated.
If <numeric expression> is 0 • • • • A random number of the sequence
generated previously is generated.
If <numeric expression> is negative • • • • A random number of a new random
number sequence is generated.
Program Example
10 ' This program generates random numbers
20 DIM A(10)
: 'Defines an array
30 PRINT "RND(1)"
40 FOR I=1 TO 10
: 'Repeats from I = 1 to 10
50 A(I)=RND(1) : 'Generates random numbers by RND(1)
60 PRINT A(I) : 'Displays the result
70 NEXT I
