JavaScript Numeric Operation

We have already performed several arithmetic operations on numbers till now. Apart from this, JavaScript provides following operations on numbers:

Operation	Description	Example
toString()	It returns numbers as strings.	var x = 123; var y = x.toString(); Output: “123”
toFixed()	It rounds a number to a given number of digits and returns it in the form of a string.	var x = 9.656; x.toFixed(0); Output: 10 x.toFixed(2); Output: 9.66
valueOf()	It returns the value of a variable	var x = 123; x.valueOf(); Output: 123
Number()	It converts variables into a number. It can also convert a date into a number.	Number(new Date(“2019-05-01”)); Output: 1556668800000
parseInt()	It parses a string and returns a whole number. It returns only the first number.	parseInt(“10.33”); Output: 10
