All Functions
Randomize Statement
FUNCTION: Rnd( )
Rnd
(
Number
)
The
Rnd
function generates a pseudo-random number greater than or equal to 0.0 and less than 1.0.
The
Number
argument is optional, but different numbers will give different pseudo-random numbers.
Note that the number generated is pseudo-random, because the same output tends to be repeated over and over. You can use the
Randomize
statement to over come this problem.
Code:
<% =Rnd() %>
Output:
0.7055475
Code:
<% =Rnd(127.89) %>
Output:
0.533424
Code:
<% =Rnd(-127.89) %>
Output:
0.6953956
Code:
<% Randomize %>
<% =Rnd() %>
Output:
0.1414095
The following code will generate a random number between any limits you choose. (Since the
Int
function always rounds down, we add one to the difference between the limits.)
Code:
<% upperlimit = 50000.0 %>
<% lowerlimit = -30000.0 %>
<% =Int((upperlimit - lowerlimit + 1)*Rnd() + lowerlimit) %>
Output:
30366
