RND Function
Purpose:
To return a random number between 0 and 1.
Syntax:
RND[(x)]
Comments:
The same sequence of random numbers is generated each time the program is run unless the
random number generator is reseeded (see RANDOMIZE statement). If x is equal to zero, then
the last number is repeated.
If x is greater than 0, or if x is omitted, the next random number in the sequence is generated.
To get a random number within the range of zero through n, use the following formula:
INT(RND*(n+1))
The random number generator may be seeded by using a negative value for x.
Examples:
10 FOR I=1 TO 5
20 PRINT INT(RND*101);
30 NEXT
RUN
53 30 31 51 5
Generates five pseudo-random numbers within the range of 0-100.
