UnitfulData

UnitfulData.jl is an extension for Unitful.jl that includes units of Information commonly encountered in Information Theory and Data Storage.

The extension also includes the exported macro @unit_custom_prefix that allows the generation of prefixed units for a general unit using a custom base and exponents and the constant prefixed_data containing the most common units in metric (base 10) and IEC (binary) format.

Defined Units and Dimensions

Data

A dimension representing Information either as Storage, Memory, or Entropy.

• bit : the most basic unit of information in computing repesented an a binary digit

• trit: a ternary unit that encode the information with three non-negative numbers

• Byte: number of bits used to encode a character of text in the computer.

• sh: the shannon is the unit of information content associated with and event occuring with probability 1/2.

• Hart: the hartley is a unit of information and entropy on base 10

• nat: the natural unit of information is a unit of information and entropy based on the natural logarithms

DataRate

A derived dimension that represate the unit of Information passing through a channel per unit of time.

• bps: the change of rate of information in bits/seconds

• Bps: the change of rate of information in Bytes/seconds
