    Number.MIN_VALUE

    Summary

    The Number.MIN_VALUE property represents the smallest positive numeric value representable in JavaScript.

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

    Description

    The MIN_VALUE property is the number closest to 0, not the most negative number, that JavaScript can represent.

    MIN_VALUE has a value of approximately 5e-324. Values smaller than MIN_VALUE ("underflow values") are converted to 0.

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

    Examples

    Example: Using MIN_VALUE

    The following code divides two numeric values. If the result is greater than or equal to MIN_VALUE, the func1 function is called; otherwise, the func2 function is called.

    if (num1 / num2 >= Number.MIN_VALUE) {
        func1();
    } else {
        func2();
    }
