TypeScript Numbers
Like JavaScript, all the numbers in TypeScript are stored as floating-point values. These numeric values are treated like a number data type. The number is used to represents both integers as well as floating-point values. The number type converts the numeric literal to an instance of the number class. The number class acts as a wrapper and manipulate the numeric literals as they were objects. TypeScript also supports Binary(Base 2), Octal(Base 8), Decimal(Base 10), and Hexadecimal(Base 16) literals.

Number Properties
The Number objects have the following set of properties:
SN | Property_Name | Description |
---|---|---|
1. | MAX_VALUE | It returns the largest possible value of a number in JavaScript and can have 1.7976931348623157E+308. |
2. | MIN_VALUE | It returns the smallest possible value of a number in JavaScript and can have 5E-324. |
3. | NEGATIVE_INFINITY | It returns a value that is less than MIN_VALUE. |
4. | POSITIVE_INFINITY | It returns a value that is greater than MAX_VALUE. |
5. | NaN | When some number calculation is not representable by a valid number, then TypeScript returns a value NaN. It is equal to a value that is not a number. |
6. | prototype | It is a static property of the Number object. It is used to assign new properties and methods to the Number object in the current document. |
Example
Output:
Number Properties: A number variable can hold maximum value: 1.7976931348623157e+308 A number variable can hold minimum value: 5e-324 Value of Negative Infinity: -Infinity Value of Positive Infinity: Infinity Example of NaN: NaN
Number Methods
The list of Number methods with their description is given below.
SN | Method_Name | Description |
---|---|---|
1. | toExponential() | It is used to return the exponential notation in string format. |
2. | toFixed() | It is used to return the fixed-point notation in string format. |
3. | toLocaleString() | It is used to convert the number into a local specific representation of the number. |
4. | toPrecision() | It is used to return the string representation in exponential or fixed-point to the specified precision. |
5. | toString() | It is used to return the string representation of the number in the specified base. |
6. | valueOf() | It is used to return the primitive value of the number. |
Example
Output:
Number Method: toExponential() 1.2345e+4 1.23e+4 Number Method: toString() 12345 3000321 Number Method: toFixed() 13 12.879 Number Method: toLocaleString() 12,667.976 Number Method: toPrecision() 1e+1 12.6 Number Method: tovalueOf() [Number: 123] 123 number
