Description
The MAX_VALUE
property has a value of approximately 1.79E+308
, or 21024. 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
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(); }
