Computers carry out their operations or communicate with other resources through binary language. Binary language is the basic language of digital devices which includes 0 and 1 to communicate with other resources. Binary language is not recommended for standard numeric formats.
Decimal is the standard format for the display of numerical or number data types. Decimal consists of 0-9 numerical. Decimal is recommended for the daily life data display. Hence, it is necessary to convert binary to decimal for an efficient user experience.
Here, we will emphasize on “How to convert binary to number in C#”.
Why Is There A Need To Convert Binary To Number In C#?
Let us discuss the real-life need for conversion for programmers. What can be scenarios in which programmers need to convert binary data into numbers?
- Decimal output – If the output of the query is decimal instead of binary or the user requests decimal data, then programmers have to convert binary data into decimal.
- Standard data display – Most of the time, the display of the query results or data display is to be done in the standard format. This standard format can be achieved through only decimal format.
Hope this help you to understand – “ how to change binary to number in C# ”.
Different Approaches To Convert Binary To Number In C#
Converting binary data to numbers can be an essential task for the programmer to develop the application. This conversion can be achieved by different approaches in C# programming language. They are listed below.
- Using Convert.ToInt32 method
- Using custom algorithm
- Using LINQ class
- Using the bitwise left shift operator
- Using BigInteger class
All these five approaches are effective for the conversion. We will discuss them in detail by code and explanation in the upcoming sections. Programmers who want to excel in this conversion should practice the code to get a better understanding of the topic.
Approach 1: Using Convert.ToInt32 method
The Convert.ToInt32 method is the predefined method in C# programming language to convert the binary data into decimals or numbers. This method is very effective and beginner friendly as it is simple to apply in any application development.
Solution Code:-
using System;
// declare the public class
public class HelloWorld
{
public static void Main(string[] args)
{
// take the user input
Console.Write("Enter a binary number: ");
string binaryInput = Console.ReadLine();
// use the method for the conversion
int decimalOutput = Convert.ToInt32(binaryInput, 2);
// display the output on the console
Console.WriteLine("Decimal equivalent: " + decimalOutput);
}
}
Output:-
Enter a binary number: 1010
Decimal equivalent: 10
Explanation:-
- Create a public class for the execution of code.
- Take the user input using the write method and read all the binary numbers from it.
- Use the Convert.ToInt32 method to convert the binary numbers into number
- The Convert.ToInt32 method takes two inputs. First is the binary variable and another one is the digit – 2.
- Then, print the final result on the console.
Approach 2: Using custom algorithm
In this algorithm, we will take the binary data from the user and then traverse the data using a for loop. We will use a traditional mathematical calculation to convert the data. In traditional mathematics, each binary digit is added by multiplying each unit with the base of 2.
Solution Code:-
using System;
// declare the public class
public class HelloWorld
{
public static void Main(string[] args)
{
// take the user input
Console.Write("Enter a binary number: ");
string binaryInput = Console.ReadLine();
// declare the decimal and basevalue
int decimalOutput = 0;
int baseValue = 1;
// create a loop to traverse all the binary data and use the method to carry out the conversion
for (int i = binaryInput.Length - 1; i >= 0; i--)
{
if (binaryInput[i] == '1')
{
decimalOutput += baseValue;
}
baseValue *= 2;
}
// display the output on the console
Console.WriteLine("Decimal equivalent: " + decimalOutput);
}
}
Output:-
Enter a binary number: 1010010
Decimal equivalent: 82
Explanation :
- Create a public class for the execution of code.
- Take the user input using the write method and read all the binary numbers from it.
- Create two variables to declare the Decimal value and base value for the loop traverse
- Use for loop to traverse all the binary data as the method is capable to convert only one binary number at a time.
- Use the custom algorithm to convert the binary numbers into number
- Save the resulting values in a decimal variable.
- Then, print the final result on the console.
Approach 3: Using LINQ
The LINQ library is the extension of C# programming to convert and use mathematical expressions. To achieve the conversion, we will use this library by using Math.Pow() method.
Solution Code:-
using System;
using System.Linq;
public class HelloWorld
{
public static void Main(string[] args)
{
// take the user input
Console.WriteLine("Enter a binary number: ");
string binaryInput = Console.ReadLine();
// declare the decimal variable and use the method for the conversion
int decimalOutput = binaryInput
.Reverse()
.Select((c, i) => c == '1' ? (int)Math.Pow(2, i) : 0)
.Sum();
// display the output on the console
Console.WriteLine("Decimal equivalent: " + decimalOutput);
}
}
Output:-
Enter a binary number: 10111 Decimal equivalent: 7
Explanation :
- Create a public class for the execution of code.
- Take the user input using the write method and read all the binary numbers from it.
- Create a decimal variable and use the LINQ method for the conversion.
- Then, print the final result on the console.
Approach 4: Using the bitwise left shift operator
The bitwise left shift operator is another method for the conversion. Programmers have to use the loop method to traverse all the binary data. Then, we use the bitwise left shift operator to store the decimal data in the variable.
Solution Code:-
using System;
public class HelloWorld
{
public static void Main(string[] args)
{
// take the user input
Console.Write("Enter a binary number: ");
string binaryInput = Console.ReadLine();
// declare the decimal variable to store the decimal output
int decimalOutput = 0;
// create a loop to traverse the binary data
for (int i = binaryInput.Length - 1, j = 0; i >= 0; i--, j++)
{
int binaryDigit = binaryInput[i] - '0';
// use the bit-wise operator
decimalOutput += binaryDigit << j;
}
// display the output on the console
Console.WriteLine("Decimal equivalent: " + decimalOutput);
}
}
Output:-
Enter a binary number: 111000
Decimal equivalent: 56
Explanation :
- Create a public class for the execution of code.
- Take the user input using the write method and read all the binary numbers from it.
- Create a decimal variable and use the for loop and bitwise left shift operator method for the conversion.
- Then, print the final result on the console.
Approach 5: Using BigInteger class
This class has the BigInteger method to convert binary data into decimals or numbers. This method has the pre-defined syntax in the BigInteger class.
But, it requires external resources. Also, this method is not applicable to online compilers as they miss the external dependencies.
Sample code :
using System;
using System.Numerics;
public class HelloWorld
{
public static void Main(string[] args)
{
// take the user input
Console.Write("Enter a binary number: ");
string binaryInput = Console.ReadLine();
// declare the variable to store the decimal value
int decimalOutput = 0;
// create a loop to traverse the binary data
for (int i = binaryInput.Length - 1, j = 0; i >= 0; i--, j++)
{
int binaryDigit = binaryInput[i] - '0';
// use the method
decimalOutput += binaryDigit * BigInteger.Pow(2, j);
}
// display the output on the console
Console.WriteLine("Decimal equivalent: " + decimalOutput);
}
}
Output :
Enter a binary number: 1101010011010
Decimal equivalent: 6810
Explanation :
- Create a public class for the execution of code.
- Take the user input using the write method and read all the binary numbers from it.
- Create a decimal variable and use the for loop and BigInteger class method for the conversion.
- Then, print the final result on the console.
All the above approaches will you to understand “ How to convert binary to number in C# ”.
