React Js Remove leading Zero from Number
React Js Remove leading Zero from Number:To remove a leading zero from a number in React.js, you can utilize one of the following methods:
-
Using the parseInt function: Convert the number to a string, apply parseInt with a radix of 10 (to ensure decimal interpretation), and store the result. This will remove any leading zeros. Example:
const parsedNumber = parseInt(number.toString(), 10); -
Using the Number constructor: Create a new Number object by passing the number as an argument, which automatically removes leading zeros. Example:
const newNumber = new Number(number); -
Using the parseFloat function: Similar to parseInt, convert the number to a string, apply parseFloat, and store the result. This will remove leading zeros and any trailing decimal places if present. Example:
const parsedFloat = parseFloat(number.toString());
