Contents 1 Summary 2 Description 3 Examples 3.1 Example: Using MIN_VALUE

[edit] Summary

The smallest positive numeric value representable in JavaScript.

Property of Number
Implemented in:	JavaScript 1.1, NES 2.0
ECMA Version:	ECMA-262

[edit] 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.

[edit] Examples

[edit] 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()
