[edit] Summary

The maximum numeric value representable in JavaScript.

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

[edit] 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.

[edit] 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();
