Python program to convert hex string to decimal

Python program to convert int to exponential

Last Updated : 05 Jan, 2022

Given a number of int type, the task is to write a Python program to convert it to exponential.

Examples:

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 format 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
