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:

# 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
