```Input: 19
Output: 1.900000e+01

Input: 2002
Output: 2.002000e+03

Input: 110102
Output: 1.101020e+05```

Approach:

• We will first declare and initialise an integer number
• Then we will use formate method to convert the number from integer to exponential type.
• Then we will print the converted value.

Syntax:

`String {field_name:conversion} Example.format(value)`

Errors and Exceptions:

ValueError: Error occurs during type conversion in this method.

More parameters can be included within the curly braces of our syntax. Use the format code syntax {field_name: conversion}, where field_name specifies the index number of the argument to the str.format() method, and conversion refers to the conversion code of the data type.

Example:

## Python3

 `# Python program to convert int to exponential`` ` `# Declaring the integer number``int_number ``=` `110102`` ` `# Converting the integer number to exponential number``exp_number ``=` `"{:e}"``.``format``(int_number)`` ` `# Printing the converted number``print``(``"Integer Number:"``,int_number)``print``(``"Exponent Number:"``,exp_number)`

Output:

```Integer Number: 110102
Exponent Number: 1.101020e+05```
