Need help converting numbers to words

I am trying to convert number to word from RDLC report:

        If decimalPlace > 0 Then
            wholeNo = numb.Substring(0, decimalPlace)
            points = numb.Substring(decimalPlace + 1)
            If Convert.ToInt32(points) > 0 Then
                andStr = "point"
                ' just to separate whole numbers from points
                pointStr = translateCents(points)

        val = [String].Format("{0} {1}{2} {3}", translateWholeNumber(wholeNo).Trim(), andStr, pointStr, endStr)

I am getting wrong output from transformation.

For a 52001

given output Fifty Two Thousand and Hundred One

. However, it should be Fifty Two Thousand and One

.
