The JavaScript Number is an object that can represent numeric values like integer, float, hexadecimal, decimal, etc. It acts as a wrapper object for primitive numeric values. It has various methods and properties that are used to perform different tasks on numbers. The following table shows some static properties of the Number object that can be used throughout a program as constants.
Property:
- MAX_VALUE: It returns the maximum number value that is supported in JavaScript.
- MIN_VALUE: It returns the smallest positive numeric value that is closest to 0, but, not the most negative number.
- NEGATIVE_INFINITY: It represents the negative infinity value.
- POSITIVE_INFINITY: It represents the positive infinity value.
- MIN_SAFE_INTEGER: It represents the minimum safe integer in JavaScript.
- NaN: It is used for representing a value that is not a legal number.
The below examples demonstrate how these properties of the Number are used.
Example 1: In this example, we find out the maximum and minimum values supported in JavaScript.
Javascript
console.log('Maximum Value:', Number.MAX_VALUE); console.log('Minimum Value:', Number.MIN_VALUE); |
Console Output:
Maximum Value: 1.7976931348623157e+308 Minimum Value: 5e-324
Example 2: In this example, we find out the positive and negative infinity values in JavaScript.
Javascript
console.log('Negative Infinity:', Number.NEGATIVE_INFINITY); console.log('Positive Infinity:', Number.POSITIVE_INFINITY); |
Console Output:
Negative Infinity: -Infinity Positive Infinity: Infinity
