Package keccak implements the Keccak (SHA-3) hash algorithm. See http://keccak.noekeon.org.

This package provides a Go implementation of JSON Web Tokens and supports the parsing and verification as well as the generation and signing of JSON Web Tokens. The currently supported signing algorithms are HMAC SHA, RSA, RSA-PSS, and ECDSA, though hooks are present for adding your own.

pkcs8 implements functions to process private keys in PKCS#8 format, as defined in RFC 5208 and RFC 5958. It can handle both unencrypted PKCS#8 PrivateKeyInfo format and EncryptedPrivateKeyInfo format with PKCS#5 (v2.0) algorithms.

This package provides primitives for generating random values.

This package is an external copy of the Go standard library's internal ChaCha20 package.

This package provides cryptography for Go. This version of the package is a fork that adds a more up-to-date OpenPGP implementation. It is completely backwards compatible with golang.org/x/crypto, the official package.

blake3 is an implementation of BLAKE3 with AVX2 and SSE4.1 acceleration.

This package offers overflow-checked integer arithmetic operations for int,int32, and int64. Each of the operations returns a result,bool combination. This was prompted by the need to know when to flow into higher precision types from the math.big library.

Package brahe defines core variable types and basic utility functions for astronomy programs using the AT-HYG (Augmented Tycho-HYG) catalog. The base file (brahe.go) defines the most widely used types in these utility functions. brahe uses the https://pkg.go.dev/gonum.org/v1/gonum/floats, Gonum floating point library for vector math.

This package provides a statistical library for Golang.

This package provides a high-performance Uint128 type that supports standard arithmetic operations. Unlike math/big, operations on Uint128 values always produce new values instead of modifying a pointer receiver. A @codeUint128 value is therefore immutable, just like uint64 and friends.

This package implements much of the decimal specification from the General Decimal Arithmetic description. This is the same specification implemented by Python’s decimal module and GCC’s decimal extension.

Gonum is a set of packages designed to make writing numerical and scientific algorithms productive, performant, and scalable. It provides libraries for matrices and linear algebra; statistics, probability distributions, and sampling; tools for function differentiation,integration, and optimization; network creation and analysis

Package fastdiv implements fast division, modulus and divisibility checks for divisors known only at runtime based on paper: Faster Remainder by Direct Computation: Applications to Compilers and Software Libraries.

This package provides a IEEE 754 half-precision floating-point format (binary16) with IEEE 754 default rounding for conversions. IEEE 754-2008 refers to this 16-bit floating-point format as binary16.

This package implements a functionality for fitting statistical model. Additional Go packages include glm for Generalized Liner Models and duration for survival analysis. All models can be fit with maximum (or quasi-maximum) likelihood estimation, with optional L1 (Lasso) or L2 (ridge) penalization.

Package mathutil provides utilities supplementing the standard math and math/rand packages.

Dstream is a package for manipulating streams of typed, multivariate data in Go. A Dstream is a dataframe-like container that holds a rectangular array of data in which the columns are variables and the rows are cases or observations.

Dstream is designed to handle large datasets, where it is not possible to load all data for all variables into memory at once. To achieve this, Dstream utilizes a chunked, column-based storage format. A chunk contains the data for a contiguous block of rows. The data are stored by variable (column-wise) in typed Go slices. Only one chunk of the Dstream is held in memory at one time.

These packages provide more specialized math routines than are available in the standard Go math package. go-moremath currently focuses on statistical routines, with particular focus on high-quality implementations and APIs for non-parametric methods.

gg is a plotting package for Go inspired by the Grammar of Graphics.

Package bigfft implements multiplication of big.Int using FFT (Schonhage-Strassen method for multiplying integers).

Package decimal implements an arbitrary precision fixed-point decimal. Features:

• the zero-value is 0, and is safe to use without initialization

• addition, subtraction, multiplication with no loss of precision

• division with specified precision

• database/sql serialization/deserialization

• JSON and XML serialization/deserialization

This package provides utilities for performing set operations on 1-dimensional intervals, such as time ranges.

This package provides additional operations for the standard library's big.Float type, including natural logarithm, exponentiation, and power functions for arbitrary-precision floating-point numbers.
