I'm writing a program for my visual basic class that computes the prices of cans per pound. I have the program running, but I need to round the cents up to the nearest dollar. How can I do this in vb? Is it possible to round a decimal variable?
I'm sorry if this sounds stupid, I am a newb lol.
Here is my code.
Public Class Form1
Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
'Variables
Dim cans As Integer
Dim canPounds As Integer
Dim canPoundTotal As Decimal
Dim canWorth As Decimal = 0.75
Dim cansNeeded As Integer
开发者_运维百科 'Conversions
cans = Convert.ToInt32(txtGoal.Text)
'Calculation
canPounds = cans / 24
canPoundTotal = canPounds * canWorth
cansNeeded = 33000 - cans
If cboNeed.SelectedIndex = 0 Then
lblOutput.Text = cansNeeded.ToString + " cans need to be collected to reach your goal"
ElseIf cboNeed.SelectedIndex = 1 Then
lblOutput.Text = canPoundTotal.ToString("C") & " will be earned by collecting cans for recycling"
End If
End Sub
Private Sub cboNeed_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboNeed.SelectedIndexChanged
If cboNeed.SelectedIndex = 0 Then
lblDesc.Text = "Target Goal Amount"
btnCalculate.Text = "Find Target Amount of Cans"
ElseIf cboNeed.SelectedIndex = 1 Then
lblDesc.Text = "Cans Collected"
btnCalculate.Text = "Find Amount Earned"
End If
End Sub
End Class
You can use the function: Math.Round(value)
