Common (CMN) is a modern, fast, and user-friendly library that makes it easy to access a wide range of mathematical and cryptographic constants.
The Common (CMN) uses the serde crate to serialize and deserialize the data.
The library has three modules:
The following table lists the most important mathematical and cryptographic constants available in the Common (CMN) library:
| Constants | Description | Example | | --- | --- | --- | | AVOGADRO | Avogadro's constant is the number of atoms or molecules in one mole of a substance. | The number of atoms in 12 grams of carbon-12 is 6.02214076 × 10^23. This can be used to calculate the number of atoms or molecules in a given sample. | | BOLTZMANN | Boltzmann's constant is the physical constant relating the temperature of a system to the average kinetic energy of its constituent particles. | The kinetic energy of an atom at room temperature is about 2.0 × 10^-21 joules. This can be used to calculate the temperature of a system, or to calculate the average kinetic energy of its particles. | | EULER | Euler's constant is a mathematical constant approximately equal to 2.71828. | The sum of the infinite series 1 + 1/2 + 1/3 + ... is equal to Euler's constant, e. This can be used to calculate the sum of an infinite series, or to calculate the logarithm of a number. | | GAMMA | The gamma constant is a mathematical constant approximately equal to 0.57721. | The gamma function of 2 is equal to 1. This can be used to calculate the gamma function of a number, or to calculate the factorial of a number. | | HASHALGORITHM | The hash algorithm used to generate the hash. The default is Blake3. | The hash of the string "Hello, world!" is 5eb63bbbe01eeed093cb22bb8f5acdc32790160b123138d53f2173b8d3dc3eee. This can be used to verify the integrity of data, or to create a unique identifier for a file. | | HASHCOST | The cost of the hash. | The hash cost of Blake3 is 2^128. This can be used to determine how secure a hash algorithm is. | | HASHLENGTH | The length of the hash. | The hash length of Blake3 is 32 bytes. This can be used to determine how much space is required to store the hash output. | | PHI | The golden ratio is a number approximately equal to 1.618033988749895. | The golden ratio can be used to create a symmetrical design, or a design that is pleasing to the eye. | | Pi (π) | Pi is the ratio of a circle's circumference to its diameter. | The circumference of a circle with a radius of 1 is equal to pi. This can be used to calculate the circumference, area, and volume of circles, spheres, and other geometric shapes. | | PLANCK | Planck's constant is a physical constant that is approximately equal to 6.62607015 × 10^−34 joule seconds. | The energy of a photon of light with a wavelength of 500 nanometers is equal to Planck's constant multiplied by the frequency of the light. This can be used to calculate the energy of photons and other elementary particles. | | SILVERRATIO | The silver ratio is a number approximately equal to 1.414213562373095. | The silver ratio can be used to create a symmetrical design, or a design that is pleasing to the eye. | | SPECIALCHARS | A list of special characters. | The special characters are: !@#$%^&*()+-={}[]|\:;"'<>,.? | | SQRT2 | The square root of 2 is a number approximately equal to 1.414213562373095. | The area of a circle with a radius of 1 is equal to the square root of 2. This can be used to calculate the area and volume of circles, spheres, and other geometric shapes. | | SQRT3 | The square root of 3 is a number approximately equal to 1.732050807568877. | The area of a circle with a radius of 1 is equal to the square root of 3. This can be used to calculate the area and volume of circles | SQRT5 | The square root of 5 is a number approximately equal to 2.23606797749979. | The area of a circle with a radius of 1 is equal to the square root of 5. | | TAU | Tau is a number approximately equal to 6.283185307179586. | The circumference of a circle with a radius of 1 is equal to tau. |
It takes just a few minutes to get up and running with Common (CMN).
To install Common (CMN), you need to have the Rust toolchain installed on your machine. You can install the Rust toolchain by following the instructions on the Rust website.
Once you have the Rust toolchain installed, you can install Common (CMN) using the following command:
shell
cargo install cmn
You can then run the help command to see the available options:
shell
cmn --help
The minimum supported Rust toolchain version is currently Rust 1.69.0 or later (stable). It is recommended that you install the latest stable version of Rust.
Common (CMN) is supported and tested on the following platforms:
