Number.MAX_VALUE

{{JSRef}}

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

{{InteractiveExample("JavaScript Demo: Number.MAX_VALUE")}}

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+308

console.log(multiply(1.7976931348623157e308, 2));
// Expected output: "Process as Infinity"

Value

2¹⁰²⁴ - 2⁹⁷¹, or approximately 1.7976931348623157E+308.

Description

Values larger than MAX_VALUE are represented as {{jsxref("Infinity")}} and will lose their actual value.

Because MAX_VALUE is a static property of {{jsxref("Number")}} , you always use it as Number.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 to MAX_VALUE, the func1 function is called; otherwise, the func2 function is called.

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