Accounting.js
accounting.js is a JavaScript library and utility suite for formatting localized numbers and currency strings, rounding decimal values, and parsing currency strings. It provides tools to transform numeric values into human-readable strings using language-specific separators and custom symbols.
The library includes a currency string parser to extract raw numerical values from formatted strings by removing symbols and separators. It also features a floating point rounding tool designed to prevent binary precision errors during financial calculations.
Additional capabilities cover the vertical alignment of currency symbols and decimal points for financial tables. The toolset also supports localized number formatting and the conversion of numbers or arrays of numbers into strings with specific precision settings.
