'VB.Net program to demonstrate the CDbl() function.

Module Module1

    Sub Main()
        Dim num As Double = 0

        Dim n1 As Single = 10.25
        Dim n2 As Integer = 12
        Dim n3 As Decimal = 25.35
        Dim n4 As String = "122"

        num = CDbl(n1)
        Console.WriteLine("Double Number: {0}", num)

        num = CDbl(n2)
        Console.WriteLine("Double Number: {0}", num)

        num = CDbl(n3)
        Console.WriteLine("Double Number: {0}", num)

        num = CDbl(n4)
        Console.WriteLine("Double Number: {0}", num)
    End Sub
    
End Module

Output:

Double Number: 10.25
Double Number: 12
Double Number: 25.35
Double Number: 122
Press any key to continue . . .

Explanation:

In the above program, we created a module Module1 that contains a Main() method. In the Main() method, we created five variables num, n1, n2, n3, and n4 that are initialized with 0, 10.25, 12, 25.35, and "122".

num = CDbl(n1)
Console.WriteLine("Double Number: {0}", num)

num = CDbl(n2)
Console.WriteLine("Double Number: {0}", num)

num = CDbl(n3)
Console.WriteLine("Double Number: {0}", num)

num = CDbl(n4)
Console.WriteLine("Double Number: {0}", num)

In the above code, we converted the value of specified variables into double numbers and printed them on the console screen.
