How To Compute Rate of Change (ROC) in VB.NET?

@irwin 

To compute the Rate of Change (ROC) in VB.NET, you can use the following formula:

ROC = (Current Value - Previous Value) / Previous Value * 100

Here is an example code snippet to calculate the ROC in VB.NET:

1
2
3

Public Function CalculateROC(currentValue As Double, previousValue As Double) As Double
    Return ((currentValue - previousValue) / previousValue) * 100
End Function

You can call this function and pass in the current and previous values to calculate the ROC. For example:

1
2
3
4
5
6

Dim currentValue As Double = 50
Dim previousValue As Double = 45

Dim roc As Double = CalculateROC(currentValue, previousValue)

Console.WriteLine("Rate of Change (ROC): " & roc & "%")

This code snippet will output the Rate of Change between the current and previous values in percentage.
