Currency Formatting
- numeral:
numeral
supports currency formatting as one of its features. It allows for customizable currency formats, including setting symbols, decimal places, and thousand separators, making it versatile for various formatting needs. - intl:
The
Intl
API provides built-in support for currency formatting based on the user's locale. It is highly accurate and leverages the browser's native capabilities to format currency values according to international standards. - currency.js:
currency.js
focuses on precise currency representation and formatting. It allows for customizable formatting, including setting decimal places and currency symbols, while ensuring accuracy in calculations and display. - currency-formatter:
currency-formatter
specializes in formatting currency values according to locale and currency code, making it easy to display values accurately for different regions. It supports multiple currencies and allows for quick formatting with minimal configuration. - accounting-js:
accounting-js
provides simple currency formatting with customizable symbols, decimal places, and thousand separators. It is straightforward and effective for basic currency display needs.
Precision and Accuracy
- numeral:
numeral
provides accurate formatting and manipulation of numbers, but it does not guarantee precision in calculations. It is important to manage precision manually, especially when dealing with large numbers or fractional values. - intl:
The
Intl
API does not handle calculations; it focuses on accurate formatting of numbers, dates, and currencies based on locale. For precision in financial applications, additional handling is required during calculations. - currency.js:
currency.js
is designed for precision in currency calculations, addressing floating-point issues common in JavaScript. It provides accurate arithmetic operations, making it suitable for financial applications where precision is critical. - currency-formatter:
currency-formatter
is primarily focused on accurate formatting rather than calculations. It ensures that currency values are displayed correctly according to the specified locale and currency code, but it does not perform arithmetic operations. - accounting-js:
accounting-js
handles precision well for formatting and basic arithmetic operations. However, it is not specifically designed for high-precision calculations, so care should be taken with complex financial computations.
Arithmetic Operations
- numeral:
numeral
provides basic arithmetic capabilities, but it is not its primary focus. The library allows for manipulation of numbers, including currency, but for complex calculations, additional handling may be required. - intl:
The
Intl
API does not perform arithmetic operations. It is solely for formatting numbers, dates, and currencies according to locale. Arithmetic must be handled using standard JavaScript methods or other libraries. - currency.js:
currency.js
excels in arithmetic operations with currency values. It supports addition, subtraction, multiplication, and division while maintaining precision. The library is designed to handle calculations safely, making it ideal for financial applications. - currency-formatter:
currency-formatter
does not provide arithmetic operations. It is focused on formatting currency values rather than performing calculations. For arithmetic, you would need to handle it separately. - accounting-js:
accounting-js
supports basic arithmetic operations like addition, subtraction, multiplication, and division. It also provides functions for rounding and formatting numbers, making it useful for simple financial calculations.
Localization Support
- numeral:
numeral
supports localization to some extent, allowing for custom number and currency formats. However, it does not provide automatic localization based on the user's settings, so developers need to implement it manually. - intl:
The
Intl
API is built for localization and provides robust support for formatting numbers, dates, and currencies according to the user's locale. It is highly flexible and accurate, making it ideal for applications that require comprehensive localization features. - currency.js:
currency.js
has basic localization capabilities, allowing for customizable currency formatting. However, it does not provide extensive support for multiple locales or automatic localization based on user settings. - currency-formatter:
currency-formatter
provides excellent localization support, allowing currency formatting based on locale and currency code. It is designed to handle multiple currencies and regions, making it easy to display values accurately for different audiences. - accounting-js:
accounting-js
offers limited localization support, primarily for formatting numbers and currencies. It allows customization of symbols and separators, but it does not provide built-in support for multiple locales.
Ease of Use: Code Examples
- numeral:
Number Formatting with
numeral
// Import the library import numeral from 'numeral'; // Format a number as currency const formattedCurrency = numeral(1234567.89).format('$0,0.00'); console.log(formattedCurrency); // Output: $1,234,567.89 // Perform basic arithmetic const sum = numeral(100).add(200); console.log(sum.value()); // Output: 300
- intl:
Currency Formatting with
Intl
API`// Format currency using the Intl API const amount = 1234567.89; const formatted = new Intl.NumberFormat('en-US', { style: 'currency', currency: 'USD', }).format(amount); console.log(formatted); // Output: $1,234,567.89
- currency.js:
Currency Operations with
currency.js
// Import the library import Currency from 'currency.js'; // Create a currency instance const amount = Currency(1234.56); // Format the currency console.log(amount.format()); // Output: $1,234.56 // Perform arithmetic operations const total = amount.add(100); console.log(total.format()); // Output: $1,334.56
- currency-formatter:
Currency Formatting with
currency-formatter
// Import the library import { format, parse } from 'currency-formatter'; // Format a number as currency const formatted = format(1234567.89, { code: 'USD' }); console.log(formatted); // Output: $1,234,567.89 // Parse a currency string const parsed = parse('$1,234,567.89'); console.log(parsed); // Output: 1234567.89
- accounting-js:
Simple Currency Formatting with
accounting-js
// Import the library import accounting from 'accounting-js'; // Format a number as currency const formattedCurrency = accounting.formatMoney(1234567.89); console.log(formattedCurrency); // Output: $1,234,567.89 // Perform basic arithmetic const sum = accounting.add(100, 200); console.log(sum); // Output: 300
