Odd or Even

This will check whether a number is odd or even , this is a common function found on other programming sites for different languages , lets look at our function.

<%
function OddOrEven(ByVal intNumber)
If (intNumber MOD 2 = 0 ) Then
Response.Write ("Your number is even<br>")
Else
Response.Write ("Your number is odd<br>")
End If
end function
%>

This is a fairly simple example to understand , we get the user entered number (intNumber) and then we use the modulus operator (MOD) to work out the remainder after division . Of course if you divide an even number by 2 there will be no remainder and alternately an odd number there will be a remainder.

Now we will test this function

<%
OddOrEven(2)
OddOrEven(97)
%>

This works out whether 2 and 97 are odd or even
