Binary to Decimal


Conversion of binary to decimal (base-2 to base-10) Given that all computer and digital systems are based on the binary numbering system, it is crucial to comprehend the notion of numbers and back.

The Base-of-10 numbering system, often known as the decimal or "denary" counting system, assigns each digit in a number one of ten potential values, or "digits," ranging from 0 to 9, as in the example 21310. (Two Hundred and Thirteen).


However, the decimal numbering system also has the addition (+), subtraction (-), multiplication (*), and division (*) operations in addition to its ten digits (0–9).

A decimal numbering system uses a base, q, along with a set of symbols, b, to define the weight of each digit in a number. In a decimal system, each digit has a value ten times larger than its previous number.

The six in sixty, for instance, is weighted less heavily than the six in six hundred. Then, in a binary numbering system, we require a method of converting from Decimal to Binary and vice versa.

The decimal system of numbering
Each integer number column in the decimal, , base-10 (den), or denary numbering system contains values of units, tens, hundreds, thousands, etc. as we progress the number along the column from right to left. These numbers are represented mathematically as 100, 101, 102, 103, etc.

Then, a higher positive power of 10 is shown by each position to the left of the decimal point. Similar to whole numbers, fractional numbers have a weight that changes from negative to positive as we move from left to right, such as 10-1, 10-2, 10-3, etc.


The binary system of numbers
All digital and computer-based systems use the binary numbering system, which is the most fundamental one. Binary numbers adhere to the same set of laws as decimal numbers. The binary numbering system, however, uses powers of two rather than the powers of ten used by the decimal system, allowing for a binary to decimal conversion from base-2 to base-10.

A situation in digital logic and computer systems can be represented by either a logic level "1" or "0," and each "0" and "1" is regarded as a single digit in a Base-of-2 (bi) or "binary numbering system."
