How to separate double number

Hi everyone,
Somebody can help me , please? I have VB 2008 Exp edition and I'm starting to learn something about programing! The question is: how can I extract the numbers behind the point.
For example:
I have the double number 12.345 - so I need to separate the number 12 from 0.345, because I need them both, even the number 12 and even the number 0.345!! For example I'll use 12 * 123 and 0.345 * 456!!!!
I hope it's clear! Thank's very much in advance!

Math.Floor can give you the integer part of the double, and then a simple minus should give you the decimal part.

Code:

Module Module1

    Sub Main()
        Dim d As Double = 123.456
        Dim i As Integer
        i = Math.Floor(d)
        'd - i can give you the decimal part
    End Sub

End Module
