Math class in C#

Math Class in C#

Introduction

Today, in this article let's play around with one of the interesting and most useful concept in C#.

Question: What is math class?

In simple terms "It provides rich set of mathametical calculations with rich set of methods as Min, Abs, Max, Sqrt and so on".

Step 1: Create a new WebForm project

Step 2: The complete code of WebForm1.aspx looks like this

            </table>
        </div>
    </center>
    </form>

Step 3: The complete code of WebForm1.aspx.cs looks like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace MathClassApp
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            TextBox2.Focus();
        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(TextBox2.Text))
            {
                Label5.Text = "Please Enter Some Values";
                Label5.ForeColor = System.Drawing.Color.Red;
            }
            else
            {
                Label5.Text = "SquareRoot Result is: " + Math.Sqrt(double.Parse(TextBox2.Text));
                Label5.ForeColor = System.Drawing.Color.Green;
                TextBox1.Text = string.Empty;
                TextBox2.Text = string.Empty;
            }
        }

        protected void Button2_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))
            {
                Label5.Text = "Please Enter Some Values";
                Label5.ForeColor = System.Drawing.Color.Red;
            }
            else
            {
                Label5.Text = "Maximum Value is: " + Math.Max(double.Parse(TextBox2.Text), double.Parse(TextBox1.Text));
                Label5.ForeColor = System.Drawing.Color.Green;
                TextBox1.Text = string.Empty;
                TextBox2.Text = string.Empty;
            }
        }

        protected void Button3_Click(object sender, EventArgs e)
        {
            if (string.IsNullOrEmpty(TextBox1.Text) || string.IsNullOrEmpty(TextBox2.Text))
            {
                Label5.Text = "Please Enter Some Values";
                Label5.ForeColor = System.Drawing.Color.Red;
            }
            else
            {
                Label5.Text = "Minimum Value is: " + Math.Min(double.Parse(TextBox2.Text), double.Parse(TextBox1.Text));
                Label5.ForeColor = System.Drawing.Color.Green;
                TextBox1.Text = string.Empty;
                TextBox2.Text = string.Empty;
            }
        }
    }
}

Step 4: The output of the application looks like this

Step 5: The minimum result output of the application looks like this
