MIN_VALUE

The smallest positive numeric value representable in JavaScript.

Property of

Number

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 2.22E-308. Values smaller than MIN_VALUE ("underflow values") are converted to 0.

MIN_VALUE is a static, read-only property of Number. As a result, you always use it as Number.MIN_VALUE, rather than as a property of a Number object you create.

Example

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()
