get the integer after decimal in javascript
In JavaScript, there are a couple of ways to get the integer after a decimal. The easiest way is to use the Math.round()
and Math.floor()
methods.
// Use Math.round()
// Round to the nearest integer
let number = 4.6;
let roundedNumber = Math.round(number);
console.log(roundedNumber); // Output: 5
// Use Math.floor()
// Round down to the nearest integer
let number = 4.6;
let roundedNumber = Math.floor(number);
console.log(roundedNumber); // Output: 4
You can also use the parseInt()
and parseFloat()
methods to get the integer after the decimal.
// Use parseInt()
// Parse a string and return an integer
let number = "4.6";
let roundedNumber = parseInt(number);
console.log(roundedNumber); // Output: 4
// Use parseFloat()
// Parse a string and return a float
let number = "4.6";
let roundedNumber = parseFloat(number);
console.log(roundedNumber); // Output: 4.6
You can also use the toFixed()
method to convert a number to a string, keeping a specified number of decimals.
// Use toFixed()
// Return a number as a string, keeping a specified number of decimals
let number = 4.6;
let roundedNumber = number.toFixed(0);
console.log(roundedNumber); // Output: 5
These are just a few of the ways you can get the integer after a decimal in JavaScript. Depending on your requirements, you can choose the best solution for your project.
