Public Shared Function SomeFunc(ByVal value As Double) As Double
If ((value - Math.Truncate(value)) < 0.5) Then
Return (value - (value - Math.Truncate(value)))
End If
If ((value - Math.Truncate(value)) > 0.6) Then
Return ((value - (value - Math.Truncate(value))) + 1)
End If
Return value 'Utak-atik disini
End Function
Console.WriteLine(Class1.someFunc(3.44)) 'output 3
Console.WriteLine(Class1.someFunc(3.55)) 'output 3.55
Console.WriteLine(Class1.someFunc(3.66)) 'output 4

Pembulatan kebawah pakai Floor, keatas paka Ceiling. Contoh nominal 125533,
#kebawah -> Math.Floor(125533/100.0)*100
#keatas -> Math.Ceiling(125533/100.0)*100
Kalau titik pada contoh angka anda adalah tanda desimal (bukan pemisah ribuan), caranya sedikit beda
#kebawah -> Math.Floor(125.533*10.0)/10
#keatas -> Math.Ceiling(125.533*10.0)/10Dijawab oleh: Putu Susila

Friday, February 24, 2012 3:29 PMKalau anda ingin angkanya benar-benar dibulatkan kebawah, semisal 9,9 tetap dibaca 9. Maka gunakan perintah fix(). Anda bisa cari artikel tersebut di MSDN kok.

Permsi Mod..!!
Mau tanya...
Masih agak bingung nih..
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
Dim a, b, x, y As Double
Dim i As Integer
a = TextBox1.Text
b = TextBox2.Text
x = a
y = b
For i = 1 To Val(Label8.Text)
x = x + Val(Label10.Text)
y = y + Val(Label11.Text)
ListBox1.Items.Add(x)
ListBox2.Items.Add(y)
NextNah script diatas nantinya akan menampilkan perulangan di ListBox..
trz.. bagaimana caranya biar pembulatan doublenya mnjadi 1 angka dibelakang koma
misalnya : angkanya 3,387383979634 menjadi 3,4 saja.
Klao bisa.. cepat yah mod..!! Tugas Kumpul Besok..!!
Terima Kasih..!!

Udah pernah pakai Format belum? Cara nulisnya seperti ini:
Dim a As Double = textbox1.text
Dim b as Double = Format(a,'#.#')
Kalo gak jelas juga, cari di msdn dengan kata kunci format. Contoh penggunaannya banyak banget kok. Semoga membantu.
