JavaScript Number.MAX_SAFE_INTEGER Constant
Below is the example of the Number.MIN_SAFE_INTEGER Constant.
- Example:
<scripttype="text/javascript">document.write(Number.MIN_SAFE_INTEGER);</script> Output:
9007199254740991
The JavaScript Number.MAX_SAFE_INTEGER is a constant number that represents the minimum safe integer. This constant has a value of (253 – 1). Here safe refers to the ability to represent integers and to compare them.
Example:
Number.MAX_SAFE_INTEGER + 1 === Number.MAX_SAFE_INTEGER + 2
The above expression will evaluate to true which is actually mathematically NOT correct.
Syntax:
Number.MAX_SAFE_INTEGER
Return Value: A constant number.
