C# Hello, i need help adding a working Decimal button to my c# calculator program, thanks

CODE

Form.cs

using System; using System.Windows.Forms;

namespace CalculatorForms { public partial class Form1 : Form { public Form1() { InitializeComponent(); }

int numerator; int denominator; string num=""; string denom=""; bool flag = false; double result;

private void button1_Click(object sender, EventArgs e) { if (flag == false) { num += "1"; } else { denom = "1"; } }

private void button2_Click(object sender, EventArgs e) { if (flag == false) { num += "2"; } else { denom = "2"; } }

private void button3_Click(object sender, EventArgs e) { if (flag == false) { num += "3"; } else { denom = "3"; } }

private void button4_Click(object sender, EventArgs e) { if (flag == false) { num += "4"; } else { denom = "4"; }

}

private void button5_Click(object sender, EventArgs e) { if (flag == false) { num += "5"; } else { denom = "5"; } }

private void button6_Click(object sender, EventArgs e) { if (flag == false) { num += "6"; } else { denom = "6"; } }

private void button7_Click(object sender, EventArgs e) { if (flag == false) { num += "7"; } else { denom = "7"; } }

private void button8_Click(object sender, EventArgs e) { if (flag == false) { num += "8"; } else { denom = "8"; } }

private void button9_Click(object sender, EventArgs e) { if (flag == false) { num += "9"; } else { denom = "9"; } }

private void button11_Click(object sender, EventArgs e) { if (flag == false) { num += "0"; } else { denom = "0"; } }

private void button12_Click(object sender, EventArgs e) { flag = true; }

private void button10_Click(object sender, EventArgs e) { numerator = Convert.ToInt16(num); denominator = Convert.ToInt16(denom); try { result = numerator / denominator; textBox1.Text = Convert.ToString(result); }

catch { MessageBox.Show( "Division by zero is not possible"); }

} } }

///

/// Clean up any resources being used. ///
