What Number System Units Are Supported?

Name	Symbol	Measurement System	Description
binary	bin	base-2	The binary number system, often referred to as base-2, is a fundamental numerical representation used in digital computing and information technology. Unlike the decimal system, which is based on powers of 10, the binary system relies on powers of 2, making it particularly well-suited for electronic devices and digital data storage. In the binary system, there are only two possible digits, 0 and 1, which are analogous to the on/off states of electronic switches. This simplicity is essential in the context of computing because it aligns perfectly with the binary nature of electronic circuits.
decimal	dec	base-10	The decimal number system, often called base-10, is the numerical system most commonly used by humans for everyday counting and arithmetic. It utilizes ten digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The concept behind the decimal system is that each digit's value is determined by its position within the number, with each position representing a power of 10.
hexadecimal	hex	base-16	The hexadecimal number system, often referred to as base-16, is a fundamental numerical representation used extensively in computer science and digital technology. In the hexadecimal system, there are 16 possible digits: 0-9 and A-F, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15. Each digit's value is determined by its position within the number, with each position representing a power of 16.
octal	oct	base-8	The octal number system, also known as base-8, is another numerical representation used in mathematics and computer science. In the octal system, there are eight possible digits: 0, 1, 2, 3, 4, 5, 6, and 7. Each digit's value is determined by its position within the number, with each position representing a power of 8.
