accounting.js 是一个非常小的JavaScript方法库用于对数字，金额和货币进行格式化。并提供可选的Excel风格列渲染。它没有依赖任何JS框架。货币符号等可以按需求进行定制。
formatMoney实例
formatMoney
// Default usage:
accounting.formatMoney(12345678); // $12,345,678.00
// European formatting (custom symbol and separators), could also use options object as second param:
accounting.formatMoney(4999.99, "€", 2, ".", ","); // €4.999,99
// Negative values are formatted nicely, too:
accounting.formatMoney(-500000, "£ ", 0); // £ -500,000
// Simple `format` string allows control of symbol position [%v = value, %s = symbol]:
accounting.formatMoney(5318008, { symbol: "GBP", format: "%v %s" }); // 5,318,008.00 GBP
