Praktikum Ke 3.1 FUNGSI NUMERIK A. TUJUAN PRAKTIKUM Tujuan praktikum ini adalah : 1. Memahami mengenai penggunaan numerik. 2. Membuat program numerik sederhana menggunakan VB.

B. LATIHAN DAN HASIL LATIHAN ( SCRIPT DAN HASIL) Latihan 1 Script : Module Module2 Sub Main() Dim intValue As Integer = 123 ' Konversi implisit (konversi widening) ' dari Integer ke Long Dim longValue As Long = intValue Console.WriteLine(intValue & " = " & longValue) ' Output: 123 Console.Read() End Sub End Module

Hasil :

Latihan 2 Script : Module Module2 Sub Main()

Dim intValue As Integer = CInt(intValue) Console.WriteLine(intValue & " = " & intValue) Console.ReadKey(CInt(intValue)) End Sub End Module

Hasil :

Latihan 3 Script : Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Lbl3.Text = CStr(Math.Cos(15.5)) End Sub End Class

Hasil :

Latihan 4 Script : Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label4.Text = CStr(CDbl(TextBox1.Text) + CDbl(TextBox2.Text)) End Sub End Class

Hasil :

C. TUGAS PRAKTIKUM a) Dari seluruh fungsi matematika yang ada di atas tadi, buatlah ke dalam satu form Script : Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label4.Text = CStr(CDbl(TextBox1.Text) + CDbl(TextBox2.Text)) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Lbl3.Text = CStr(Math.Cos(15.5)) End Sub End Class

Hasil :

b) message box hasil penjumlahan 2 angka yang diinputkan melalui kode program Script : Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label4.Text = CStr(CDbl(TextBox1.Text) + CDbl(TextBox2.Text)) MessageBox.Show("Hasil = " & (Label4.Text)) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Lbl3.Text = CStr(Math.Cos(15.5)) End Sub End Class

Hasil :

c) Perkalian input dari kode program Script: Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label4.Text = CStr(CInt(25) * CDbl(45)) MessageBox.Show("Hasil = " & CInt(25) * CInt(45)) End Sub Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Lbl3.Text = CStr(Math.Cos(15.5)) End Sub End Class

Hasil :

D. HASIL TUGAS RUMAH ( SCRIPT DAN HASIL) 1. Message box hasil perkalian, pembagian, pengurangan dan penambahan 2 angka yang diinputkan melalui Toolbox dalam 1 form

Script : Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label1.Text = CStr(CDbl(TextBox1.Text) + CDbl(TextBox2.Text)) Label2.Text = CStr(CDbl(TextBox1.Text) CDbl(TextBox2.Text)) Label3.Text = CStr(CDbl(TextBox1.Text) * CDbl(TextBox2.Text)) Label4.Text = CStr(CDbl(TextBox1.Text) / CDbl(TextBox2.Text)) MessageBox.Show("hasil MessageBox.Show("hasil MessageBox.Show("hasil MessageBox.Show("hasil End Sub End Class

Hasil penambahan :
