Imports System

Module Module1
Sub Main()

Dim theDecNumber As Decimal = 12345.678

Console.WriteLine("No formatting: " + theDecNumber.ToString + vbCrLf)

'Demonstrate the standard formats
Console.WriteLine("Standard Formats" + vbCrLf)
Console.WriteLine("Currency formatting: " + theDecNumber.ToString("C"))
Console.WriteLine("Exponential formatting: " + theDecNumber.ToString("E"))
Console.WriteLine("Fixed-point formatting: " + theDecNumber.ToString("F2"))
Console.WriteLine("General formatting: " + theDecNumber.ToString("G"))
Console.WriteLine("Number formatting to 2 decimal places: " + theDecNumber.ToString("N2"))
Console.WriteLine("Number formatting to 3 decimal places: " + theDecNumber.ToString("N3"))
Console.WriteLine("Number formatting to 4 decimal places: " + theDecNumber.ToString("N4"))
Console.WriteLine("Percent formatting: " + theDecNumber.ToString("P0"))

Console.WriteLine(vbCrLf + "Special Formats" + vbCrLf)

'Converting an Integer to Hexidecimal using the ToString method
Dim theIntNumber As Integer = 123456
Console.WriteLine("Hexidecimal formatting (for integers): {0} = {1}", theIntNumber, theIntNumber.ToString("X"))

'Demonstrate using custom formatting
Dim theDblNumber As Double = 1234567890
Console.WriteLine("Custom formatting: {0} to US telephone {1}", theDblNumber, theDblNumber.ToString("(###) ### - ####"))

Console.Write(vbCrLf + "Press Enter to Continue")
