We can use native JavaScript method to round to two or more places in React JS. Here we are going to create one example to use toFixed method to format the decimal numbers to 2 decimal places. ReactJs Round to two decimal placess | JavaScript Example Let’s create an example to underst...
JS retains 2 decimal places (mandatory) If the number of decimal places is greater than 2 digits, it is okay to use the above function, but if it is smaller than 2 digits, for example: Changetwodecimal (3.1) will return 3.1. If you need a format like 3.10, you need the following f...

To simplify editing, the applications will store the underlying values and the number formats separately. For example,$3.50will be represented as the value3.5with a number format that mandates a$sigil and 2 decimal places. Thezproperty of SheetJS cell objects stores the number format metadata: ...
const Decimal = require('decimal.js'); export default { // 加 add(num1, num2) { const decimalNum1 = new Decimal(num1); const decimalNum2 = new Decimal(num2); const sum = decimalNum1.plus(decimalNum2); return sum.toDecimalPlaces(2).toNumber(); ...

Includes a TypeScript declaration file:decimal.d.ts The library is similar tobignumber.js, but here precision is specified in terms of significant digits rather than decimal places, and all calculations are rounded to the precision (similar to Python's decimal module) rather than just those invol...
