Like the decimal base 10, the base is a semiprime, though it is unique as the product of the only two consecutive numbers that are both prime (2 and 3). As six is a superior highly composite number , many of the arguments made in favor of the duodecimal system also apply to the senary system.
The duodecimal system, also known as base twelve or dozenal, is a positional numeral system using twelve as its base.In duodecimal, the number twelve is denoted "10", meaning 1 twelve and 0 units; in the decimal system, this number is instead written as "12" meaning 1 ten and 2 units, and the string "10" means ten.
Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
There is no standard notation: examples from various texts include θ, ψ, q, ϕ′, ϕ c, ϕ g. This article uses θ. Geographic latitude must be used with care, as some authors use it as a synonym for geodetic latitude whilst others use it as an alternative to the astronomical latitude. "Latitude" (unqualified) should normally refer to the ...
Having a lot of factors in the number 240 sounds "neat" in an abstract mathematical way, but I'm unclear how that would ever make anything simpler in practice. (Or how it'd outweigh the constant difficulty due to the conversion being "divide or multiply by 240", instead of "just move the dot by two places" for a decimal system.)
First implemented as a compile-and-go system rather than an interpreter, BASIC emerged as part of a wider movement towards time-sharing systems. General Electric, having worked on the Dartmouth Time-Sharing System and its associated Dartmouth BASIC, wrote their own underlying operating system and launched an online time-sharing system known as Mark I featuring a BASIC compiler (not an ...
Atanasoff and Berry completed a special-purpose calculator for solving systems of simultaneous linear equations, later called the 'ABC' ('Atanasoff–Berry Computer'). This had 60 50-bit words of memory in the form of capacitors (with refresh circuits—the first regenerative memory) mounted on two revolving drums. The clock speed was 60 Hz ...
