Question

Hi, I want to convert some stuff from (and to) binary, decimal and hexadecimal numerical systems. Can you please help me?

1. Convert 1234_d to binary and hexadecimal numeral systems.
2. Convert 1100101_b to decimal and hexadecimal numeral systems.
3. Convert ABC_hex to decimal and binary numeral systems.

Answer 1

The fastest way to do it is to use your Window's (for PC users) calculator - the programmers option (in the "View" tab);

But since there are more interesting ways to convert numbers and symbols you can play around; Here are my answers:

1. Convert 1234_d to binary and hexadecimal numerical systems:

1234/2 = 617 (0)

617/2 = 308 (1)

308/2 = 154 (0)

154/2 = 77 (0)

77/2 = 38 (1)

38/2 = 19 (0)

19/2 = 9 (1)

9/2 = 4 (1)

4/2 = 2 (0)

2/2 = 1 (0)

1/2 = 0 (1)

Thus, the number 1234_d in the binary numerical system will look like: 10011010010

The number 1234_d in the hexadecimal numerical system will look like: 4D2

2. Convert 1100101_b to decimal and hexadecimal numerical systems:

1100101_b=1+4+32+64=101

Thus, the number 1100101 _b in the decimal numerical system will look like: 101

The number 1100101 _b in the hexadecimal numerical system will look like: 65

3. Convert ABC_hex to decimal and binary numeral systems:

ABC_hex in the decimal numerical system will look like: 2748

ABC_hex in the binary numerical system will look like: 101010111100

Answer 4

You can use while loop to convert int to binary:

using System;

class ConvertInt
{
    static void Main()
    {
        int x = 1234;

        while (x > 0)
        {
            Console.WriteLine(x % 2);
            x = x / 2;
        }
    }
}

Answer 5

You can use Convert.ToString for the number 1234:

using System;

class ConvertEasyWayMethod
{
    static void Main()
    {
        Console.WriteLine("Number 1234 in binary is: " + Convert.ToString(1234, 2));
        Console.WriteLine("Number 1234 in hexadecimal is: " + Convert.ToString(1234, 16));
    }
}

Answer 6

Unfortunately there is NO formatting string for binary...

For Hexadecimal you can use:

using System;
using System.Linq;

class Formatting
{
    static void Main()
    {
        int number = 1234;
        Console.WriteLine("The number 1234 in HEX is: {0:X}", number);
    }
}

For converting to binary you can use:

using System;
 
class Convert
{
    static void Main()
    {
        Console.WriteLine("Number 1234 in binary is: " + Convert.ToString(1234, 2));
     }
}

Answer 7

You can use Convert.ToString :-) Here's how:

using System;

class VariableInHexadecimalFormat
{
    static void Main()
    {
        int a = 0xFE;
        Console.WriteLine(Convert.ToString(a, 16));//HEX format
        Console.WriteLine(Convert.ToString(a, 2));//BINARY format
        Console.WriteLine(Convert.ToString(a, 10));//DECIMAL format
    }
}
