    Number.MAX_VALUE

    Summary

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

    Property attributes of Number.MAX_VALUE
    Writable no
    Enumerable no
    Configurable no

    Description

    The MAX_VALUE property has a value of approximately 1.79E+308. Values larger than MAX_VALUE are represented as "Infinity".

    Because MAX_VALUE is a static property of Number, you always use it as Number.MAX_VALUE, rather than as a property of a Number object you created.

    Examples

    Example: 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();
    }
