TheNumber.MAX_VALUE static data property represents the maximum numeric value representable in JavaScript.

Try it

function multiply(x, y) {  if (x * y > Number.MAX_VALUE) {    return "Process as Infinity";  }  return x * y;}console.log(multiply(1.7976931348623157e308, 1));// Expected output: 1.7976931348623157e+308console.log(multiply(1.7976931348623157e308, 2));// Expected output: "Process as Infinity"

Value

2¹⁰²⁴ - 2⁹⁷¹, or approximately1.7976931348623157E+308.

Description

Values larger thanMAX_VALUE are represented asInfinity and will lose their actual value. As mentioned inNumber.EPSILON, the precision of numbers depends on their magnitude. Integers can only be represented precisely up toNumber.MAX_SAFE_INTEGER, which is 2⁵³ - 1.

BecauseMAX_VALUE is a static property ofNumber, you always use it asNumber.MAX_VALUE, rather than as a property of a number value.

Examples

Using MAX_VALUE

The following code multiplies two numeric values. If the result is less than or equal toMAX_VALUE, thefunc1 function is called; otherwise, thefunc2 function is called.

if (num1 * num2 <= Number.MAX_VALUE) {  func1();} else {  func2();}
