Base 4 to Base 21

base-4

• Definition: Base-4, also known as quaternary, is a numeral system that uses four distinct symbols to represent values. These symbols are typically 0, 1, 2, and 3.

• Symbol: The symbols used in base-4 are 0, 1, 2, and 3. Each digit represents a power of 4, similar to how digits in base-10 represent powers of 10.

• Usage: Base-4 is used in various applications, including computer science and digital systems, where it can efficiently represent binary data in a more compact form.

base-21

• Definition: Base-21 is a numeral system that uses twenty-one distinct symbols to represent values. This system extends beyond the traditional ten digits of base-10, incorporating additional symbols to accommodate its higher base.

• Symbol: The symbols used in base-21 are typically represented as 0-9 for the first ten digits and then A-K for the next eleven digits. Thus, base-21 includes 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, G, H, I, J, and K.

• Usage: Base-21 is less common than other numeral systems but can be used in specialized computing contexts and for encoding information in a compact manner.

Origin of the base-4

• Base-4 has its origins in ancient numeral systems, where the concept of using a base greater than two emerged as a way to simplify calculations and representations. Its simplicity and straightforward representation make it suitable for certain mathematical applications.

Origin of the base-21

• Base-21 is a more modern development, as numeral systems evolved to meet the needs of complex computations and data representation. The expansion to a base of 21 allows for a greater range of values with fewer digits, making it useful in various theoretical and practical applications.
