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

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”));
