decimal128

Built-in exact decimal numbers for JavaScript

Zero-dependency 128-bit fixed-point decimal for Go. Exact SQL NUMERIC / PostgreSQL semantics, no heap allocation, no panics — built for money, ledgers and banking arithmetic.

Arbitrary-precision decimal arithmetic in Swift with full math functions and fixed-precision Decimal 32-, 64-, and 128-bit types.

Java library to encode and decode IEEE-754 decimals

An arbitrary-precision integer and decimal library for Mojo, also with a 128-bit fixed-point decimal type.

A Swift implementation based on the Intel Corp Decimal Floating-Point Math Library v2.2. This library uses Binary Integer Decimal (BID) encoded numbers in its implementation. Conversions to/from Densely Packed Decimal (DPD) encoded numbers are provided.

Port of the Intel Decimal Floating-Point Math Library decimal128 type to Rust.

Money money money!
