#HEX TO DECIMAL COLOR CONVERTER HOW TO#

To convert a hex to decimal, call the parseInt() function, passing the hex and 16 as the first and second arguments respectively, i.e., parseInt(hex, 16). And we’ll look at some real-world scenarios where we’ll need to do this.

It is used ubiquitously for everyday applications, mathematics, and within many other contexts.In this article, we’re going to learn how to convert a hexadecimal number to its decimal equivalent in JavaScript. The numerals that people today are accustomed to were a result of early typesetting in the late 15 th to earthly 16 th century.Ĭurrent use: The decimal numeral system is the most common system used around the world for the symbolic representation of numbers. The earliest known evidence of the Hindu-Arabic numerals being used in Europe was found in the Codex Vigilanus, a compilation of historical documents written in the year 976. The positional decimal system in use today has roots as early as around the year 500, in Hindu mathematics during the Gupta period.

Some believe that this is linked to the human hand usually having ten digits. History/origin: Numerals based on ten have been used by many cultures since ancient times including the Indus Valley Civilization, ancient Egyptians, the Bronze Age cultures of Greece, the classical Greeks, and the Romans, among others. Decimal fractions can also be represented by using a decimal point ('.'). For example, the number 111:ġ11 = 1 × 10 2 + 1 × 10 1 + 1 × 10 0 = 100 + 10 + 1 = 111Īs can be seen, even though each symbol (the '1') is the same in each position, they all have different magnitudes. It is a system that uses positional notation, where the same symbol is used in different positions, and the magnitude is determined by which 'place' the symbol holds. Decimalĭefinition: The decimal numeral system is a base-10 numeral system, also known as the Arabic number system, and is the standard system used to represent integer and non-integer numbers, using the symbols 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. This is partly due to it being easier for humans to read hexadecimal values than it is for them to read binary-coded values. Both capital A-F as well as lower case a-f are used today to represent these symbols.Ĭurrent use: The hexadecimal numeral system is widely used throughout computer system design and programming. Yet others used K, S, N, J, F, and L or even F, G, J, K, Q, and W.Īs can be seen, there were many different ways in which the values of 10 through 15 were represented in the past, showing the fairly arbitrary nature of symbol choice. In the 1950s, some used the digits 0 through 5 with a bar over each value, while others used the letters u through z. History/origin: The term hexadecimal is derived from the prefix 'hexa' from Greek for 'six' and 'decimal,' which is derived from the Latin meaning 'tenth.' The symbols A-F were not always used for the values 10 through 15 in the earlier instances of the hexadecimal system. For example, using the hex number AAA:ĪAA = 10 × 16 2 + 10 × 16 1 + 10 × 16 0 = 2560 + 160 + 10 = 2730Īs can be seen, although the symbols occupying the three positions shown are the same, 'A,' the magnitude of each is one power of 16 apart.

Being a positional numeral system means that each position represents a different magnitude. Definition: The hexadecimal numeral system is a base-16 positional numeral system that uses the same symbols as the decimal system to represent the values of zero to nine (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and the letters A, B, C, D, E, and F to represent the values of ten to fifteen.
