Information on Number Conversion

A number system is a method of expressing numbers in a consistent manner using digits and numbers. There are different number system like, Decimal, Binary, Octal, Hexadecimal. These different number systems are used in different contexts.

Decimal Number System

Decimal number system is the most commonly used number system. It is a base 10 number system. It uses 10 digits from 0 to 9. The position of each digit in a decimal number denotes the power of 10. The rightmost digit is the ones place, the next digit to the left is the tens place, the next digit to the left is the hundreds place, and so on.

An example of a decimal number is
1234₁₀ = 1×10³ + 2×10² + 3×10¹ + 4×10⁰

Hexadecimal Number System

Hexadecimal number system is a base 16 number system. It uses 16 digits from 0 to 9 and A to F. The position of each digit in a hexadecimal number denotes the power of 16. The rightmost digit is the ones place, the next digit to the left is the sixteens place, the next digit to the left is the two hundred fifty-six place, and so on.

An example of a hexadecimal number is
1234₁₆ = 1×16³ + 2×16² + 3×16¹ + 4×16⁰

How to convert Decimal to Hexadecimal?
