Package decimal provides a high-performance, arbitrary precision, floating-point decimal library. This package provides floating-point decimal numbers, useful for financial programming or calculations where a larger, more accurate representation of a number is required. In addition to basic arithmetic operations (addition, subtraction, multiplication, and division) this package offers various mathematical functions, including the exponential function, various logarithms, and the ability to compute continued fractions. While lean, this package is full of features. It implements interfaces like “fmt.Formatter” and intuitively utilizes verbs and flags as described in the “fmt” package. (Also included: “fmt.Scanner”, “fmt.Stringer”, “encoding.TextUnmarshaler”, and “encoding.TextMarshaler”.) It allows users to specific explicit contexts for arithmetic operations, but doesn't require it. It provides access to NaN payloads and is more lenient when parsing a decimal from a string than the GDA specification requires. API interfaces have been changed slightly to work more seamlessly with existing Go programs. For example, many “Quantize” implementations require a decimal as both the receiver and argument which isn't very user friendly. Instead, this library accepts a simple “int” which can be derived from an existing decimal if required. It contains two modes of operation designed to make transitioning to various GDA "quirks" (like always rounding lossless operations) easier. There are three primary goals of this library: By adhering to the General Decimal Arithmetic specification, this package has a well-defined structure for its arithmetic operations. Decimal libraries are inherently slow; this library works diligently to minimize memory allocations and utilize efficient algorithms. Performance regularly benchmarks as fast or faster than many other popular decimal libraries. Libraries should be intuitive and work out of the box without having to configure too many settings; however, precise settings should still be available. The following type is supported: The zero value for a Big corresponds with 0, meaning all the following are valid: Method naming is the same as math/big's, meaning: In general, its conventions mirror math/big's. It is suggested to read the math/big package comments to gain an understanding of this package's conventions. Arguments to Binary and Unary methods are allowed to alias, so the following is valid: Unless otherwise specified, the only argument that will be modified is the result (“z”). This means the following is valid and race-free: But this is not:

Package decimal provides a high-performance, arbitrary precision, fixed-point decimal library. The following type is supported: The zero value for a Big corresponds with 0. Its method naming is the same as math/big's, meaning: In general, its conventions will mirror math/big's. In general, operations that use the receiver z as storage will not modify z's Context. Additionally, the arguments to Binary and Unary methods are allowed to alias, so the following is valid: Compared to other decimal libraries, this package:
