This package implements a hash/displace minimal perfect hash function.

This package provides a port of the XXH3 hash algorithm to Golang. XXH3 is an extremely fast non-cryptographic hash algorithm.

PKI based identities for use in go-libp2p.

Various cryptographic utilities used by IPFS

This package implements the pseudo-random-function (PRF) HighwayHash. HighwayHash is a fast hash function designed to defend hash-flooding attacks or to authenticate short-lived messages.

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

Package xxhash implements the 64-bit variant of xxHash (XXH64) as described at https://xxhash.com/.

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.

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

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.

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

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

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

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.

This package provides a statistical library for Golang.

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.

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 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.

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

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.

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 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.
