Generate a Random Number
The Rnd function returns a value less than 1 but greater than or equal
to 0.
Note that to use the Rnd function properly you must place the Randomize
statement somewhere before it to ensure that a new random number is
generated each time the page is reloaded. Have a look at the following
code in Example 1.
Example 1;
<%
Dim MyRandomNum
Randomize
MyRandomNum = Rnd
Response.Write MyRandomNum
%>
The above code will produce a different number each time. Below are
typical numbers produced.
0.9923431
0.2924431
Example 2 below shows the code to create a number between 1-100.
Example 2;
<%
Dim MyNewRandomNum
Randomize
MyNewRandomNum = (Rnd * 100)+1
response.write MyNewRandomNum
%>
The code above will produce a number such as 55.9393933
To get rid of the decimals we can use the Int function as in example
3 below.
Example 3;
<%
Dim MyNewRandomNum
Randomize
MyNewRandomNum = Int(Rnd * 100)+1
response.write MyNewRandomNum
%>
The above code chops off the decimals and leaves you with a number
such as 55.
Note that it doesn't round the number of, it merely chops off the decimals.
To round of the number use the Round function instead of Int as is demonstrated
in example 4 below.
Example 4;
<%
Dim MyNewRandomNum
Randomize
MyNewRandomNum = Round(Rnd * 100)+1
response.write MyNewRandomNum
%>
