Method 1: By Converting Decimal Integers to Binary

The conversion of decimal to binary is defined in the following steps.

  1. First of all, divide the integer by 2.
  2. Note the remainder value and the quotient value.
  3. Repeat this process until the quotient comes down to zero.
  4. Note down the remainder values in a backward sequence.
  5. That’s the binary value for your required decimal number.

For instance, let’s convert integer 14 into binary.

14/2 = 7 (remainder value = 0)

7/2 = 3 (remainder value = 1)

3/2 = 1 (remainder value = 1)

1/2 = 0 (remainder value = 1)

Hence, the binary value for integer 14 is 1110.

Method 2: By Converting Decimal Fractions to Binary

Let's look at how decimal fractions can be converted to binary.

  1. Firstly, multiply the decimal fraction with 2.
  2. Note down the result of multiplication while distinctly writing the integer and decimal parts.
  3. Multiply the fraction resulting from multiplication by 2 until the fraction part is zero.
  4. List down the integer value results from each multiplication and write down the binary string starting with a decimal point.

For instance, let’s convert the fraction 0.125 into binary.

0.125 * 2 = 0 + 0.25

0.25 * 2 = 0 + 0.5

0.5 * 2 = 1 + 0

Hence, the binary value for the fraction 0.125 is 0.001.

Decimal Number System

The decimal number system has a base 10 and consists of 10 values, which include 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. It is a widely used number system in computer systems. The values in the decimal number system have distinct positions. Each digit has ten times more important than the next value.

The digits we use in our everyday lives are often decimal numbers, so whenever we calculate something, we prefer decimal numbers. The reason is they are accurate because if we make calculations in real numbers, we’ll never be able to get the desired result.

Binary Number System

The binary number system has base 2 and consists of only 2 values that are 0 and 1. Every digit in this number system is referred to as a bit. In computers, all the data we input is stored in the form of numbers, not letters or ASCII characters. Those numbers are known as binary numbers, which is one of the four number systems.

The binary numbers have been given a specific name where one bit is equal to one binary digit, four binary digits are called nibbles, eight figures are known as bytes, sixteen are known as words, thirty-two and sixty-four are known as double words and quadword.

Computers can also process other number systems, but since all programming is based on the binary number system, it becomes necessary to convert other numbers to this format. Also, the current supplied to the computer is taken as one and zero, where 0 represents off, and 1 represents on.

Decimal to Binary Conversion

Converting decimal to binary manually involves several intricacies and is very time-consuming. You need to follow various steps, need a decimal to binary table, and formulas to calculate values precisely to get accurate results.

You need to be careful that you don’t accidentally mix the two sets of numbers. For example, if we write “10” digit on a page, it can be taken as ten in decimal but is actually a binary number one and zero. This shows how difficult it is to convert decimal numbers to binary manually.

On the other hand, using an online decimal to binary converter you can quickly convert decimal numbers into binary numbers without any manual effort. All you have to do is enter decimal values, and press Convert to generate results quickly. In this online method, you will not only get 100% accurate results within just a few clicks but also save your time and effort.
