TypeScript | toExponential() Method

The toExponential() method in TypeScript is used to convert a number to its exponential form. This method returns a string representing the given number object in exponential notation according to the given parameter.

Syntax:

number.toExponential( [fractionDigits] )

Parameters: This method accepts a single parameter as mentioned above and described below:

fractionDigits: It is an integer value that specifies the number of digits after the decimal point. It is an optional parameter.

Return Value: The toExponential() method in TypeScript returns a string representing the number object in exponential notation with one digit before the decimal point.

Below examples illustrate the working of toExponential() method in TypeScript:

Example 1:

TypeScript

// Define a number to find the 
// exponential notation 

var num1 = 2762.30 

// Find the exponential value 

var val = num1.toExponential(); 

// Display the value 
console.log(val)

Output:

2.7623e+3

Example 2:

TypeScript

// Define a number to find the 
// exponential notation 

var num2 = 23456 

  
// Find the exponential value 
// with two digits after the 
// decimal point 

var val = num2.toExponential(2); 

  
// Display the value 
console.log(val) 

Output:

2.34e+4
