JavaScript EPSILON

Number.EPSILON is the difference between the smallest floating point number greater than 1 and 1.

Example

Example Code

javascript

Try it Yourself

let x = Number.EPSILON;

Number.EPSILON is an ES6 feature. > It does not work in Internet Explorer.

JavaScript MAX_VALUE

Number.MAX_VALUE is a constant representing the largest possible number in JavaScript.

Example

Example Code

javascript

Try it Yourself

let x = Number.MAX_VALUE;

Number Properties Cannot be Used on Variables > Number properties belong to the JavaScript Number Object. > These properties can only be accessed as Number.MAX_VALUE. > Using x.MAX_VALUE, where x is a variable or a value, > will return undefined:

Example

Example Code

javascript

Try it Yourself

let x = 6;

x.MAX_VALUE

JavaScript MIN_VALUE

Number.MIN_VALUE is a constant representing the lowest possible number in JavaScript.

Example

Example Code

javascript

Try it Yourself

let x = Number.MIN_VALUE;

Minimum and Maximum Safe Integers

ES6 added max and min properties to the Number object:

Number.MAX_SAFE_INTEGER
Number.MIN_SAFE_INTEGER

JavaScript MIN_SAFE_INTEGER

Number.MIN_SAFE_INTEGER represents the minimum safe integer in JavaScript.

Number.MIN_SAFE_INTEGER is -(253 - 1).

Example

Example Code

javascript

Try it Yourself

let x = Number.MIN_SAFE_INTEGER;

JavaScript MAX_SAFE_INTEGER

Number.MAX_SAFE_INTEGER represents the maximum safe integer in JavaScript.

Number.MAX_SAFE_INTEGER is (253 - 1).

Example

Example Code

javascript

Try it Yourself

let x = Number.MAX_SAFE_INTEGER;

JavaScript POSITIVE_INFINITY

Example

Example Code

javascript

Try it Yourself

let x = Number.POSITIVE_INFINITY;

JavaScript NEGATIVE_INFINITY

Example

Example Code

javascript

Try it Yourself

let x = Number.NEGATIVE_INFINITY;

JavaScript NaN - Not a Number

NaN is a JavaScript reserved word for a number that is not a legal number.

Examples

Example Code

javascript

Try it Yourself

let x = Number.NaN;

Safe integers are all integers from -(253 - 1) to +(253 - 1). > This is safe: 9007199254740991. This is not safe: 9007199254740992.
