Number.MAXVALUE
En esta página
The Number.MAX_VALUE static data property represents the maximum numeric value representable in JavaScript.
{{InteractiveExample("JavaScript Demo: Number.MAX_VALUE")}}
```js interactive-example 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
2<sup>1024</sup> - 2<sup>971</sup>, or approximately `1.7976931348623157E+308`.

## Description
Values larger than `MAX_VALUE` are represented as {{jsxref("Infinity")}} and will lose their actual value. As mentioned in {{jsxref("Number.EPSILON")}}, the precision of numbers depends on their magnitude. Integers can only be represented precisely up to {{jsxref("Number.MAX_SAFE_INTEGER")}}, which is 2<sup>53</sup> - 1.
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.
```js
if (num1 * num2 <= Number.MAX_VALUE) {
func1();
} else {
func2();
}
