I currently have a calculation that gets performed based on the type of operation a user chooses on my form (+, -, *, or /). I have it check their answer against the correct answer and tell them if they get the answer right or wrong. I need to know how I can check the answer when they choose a division sign that checks only the first two digits of the lbltxtAnswer label. I also currently have a validation that checks for numbers only, so if the user types in a decimal, the error message displays, which I don't want it to do. Here is my calculation and validation [code]...

I am attempting to take the decimal places of a given input, round it so there are only two decimal places, then change it to a whole number. So far I have been able to remove the integer part of the number, leaving only the decimal, but the other procedures are eluding me. Here's what I have so far: (VB 2008)
Private Function DecimalNumber(ByVal number As Double) As Double
Dim Input As Double
Dim SubtractNumber As Decimal
[Code]....
That code returns the decimal part of the input just fine, and I thought maybe multiplying it by 10 would work....but obviously you run into problems when there is more than one decimal place.
I have class representing a unit of measure with a Decimal as the numeric. Just to simplify things for this example, let's say I'm representing centimeters. I'd like to implement a ToString() method for this class. The thing is, if the numeric value is a whole number I'd like to just display the decimal as an integer. Otherwise, I'd like to keep it as a decimal. So, for example, 10.5D centimeters would display as "10.5cm", but 7.0D centimeters should display as "7cm". I'd like this to be fast and simple to read. I have a working solution, but it seems like there should be a better way.Here's a contrived example showing my first crack at it:
Public Property Units As String = "cm"
Public Property NumericValue As Decimal = 10.5D
Public Overrides Function ToString()
