Introduction
My previous article was Convert Decimal to Binary Number and in this article I explain how to convert a number expressed as a binary number to a number expressed as a decimal number. So let us first of all understand the conversion.
Binary Number: A number expressed using the base 2 number with digits 0 and 1.
Decimal Number: A number expressed using the 10 number with digits 0 to 9.
Conversion Example: Suppose we want to convert binary number 1101 to decimal. The followiing is the conversion process:
Step 1: 1* 1=1
Step 2: 0* 2=0
Step 3: 1*4=4
Step 4: 1*8=8
Its decimal value = 1 + 0 + 4 + 8 = 13.
So (1101)2 = (13)10
Use the following procedure to create it.
Step 1
First of all you must create a new Windows Store Application.
Open Visual Studio 2012
"File" -> "New" -> "Project..."
Choose "Template" -> "Visual C#" -> "Window Store app"
Choose "Blank App (XAML)" then rename the application
Step 2
Write the following XAML code in "Mainpage.Xaml" (that is available in Solution Explorer):
<Page
x:Class="binary_to_decimal_convertor_app.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:binary_to_decimal_convertor_app"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d">
<Grid Background="red">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="313*"/>
<ColumnDefinition Width="254*"/>
<ColumnDefinition Width="788*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="78*"/>
<RowDefinition Height="49*"/>
<RowDefinition Height="37*"/>
<RowDefinition Height="40*"/>
<RowDefinition Height="39*"/>
<RowDefinition Height="525*"/>
</Grid.RowDefinitions>
<TextBlock Text="Binary to Decimal Converter app" Grid.ColumnSpan="3" Grid.Row="1" Foreground="White" FontSize="20" FontFamily="Arial" TextAlignment="Center"></TextBlock>
<TextBlock Text="Enter Binary Number :" FontFamily="Arial" FontSize="15" Foreground="White" Grid.Column="1" Grid.Row="2" Grid.RowSpan="4"></TextBlock>
<TextBox x:Name="textbox1" Grid.Column="2" Grid.Row="2" Width="200" HorizontalAlignment="Left" Height="20" VerticalAlignment="Top" />
<TextBlock Text="Eqivalent Decimal Number " FontSize="15" Foreground="White" Grid.Column="1" Grid.Row="3"></TextBlock>
<TextBlock x:Name="text1" FontSize="15" Foreground="White" Grid.Column="2" Grid.Row="3" Width="200" HorizontalAlignment="Left" ></TextBlock>
<Button x:Name="button1" Grid.Column="2" Grid.Row="4" Background="Yellow" Foreground="Black" Width="150" Content="Click" Click="button1_Click"></Button>
</Grid>
</Page>
Step 3
Now write the following C# code for the button within "Mainpage.Xaml.cs".
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
namespace binary_to_decimal_convertor_app
{
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
}
private void button1_Click(object sender, RoutedEventArgs e)
{
long binum=0;
int r=0, j=1;
int decnum=0;
binum =long.Parse(textbox1 .Text );
while (binum !=0)
{
r= (int) binum % 10;
decnum =decnum +r*j;
j=j*2;
binum =binum /10;
}
text1 .Text =decnum .ToString ();
}
}
}
Step 4
Now Run your app.
