Python program to convert float to exponential

Given a float number, the task is to write a Python program to convert float to exponential.

Examples:

Input: 19.0
Output: 1.900000e+01

Input: 200.2
Output: 2.002000e+02

Input: 1101.02
Output: 1.101020e+03

Approach:

• We will first declare and initialise a float 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 float to exponential

# Declaring the float number
float_number = 1101.02

# Converting the float number to exponential number
exp_number = "{:e}".format(float_number)

# Printing the converted number
print("Float Number:",float_number)
print("Exponent Number:",exp_number)

Output:

Float Number: 1101.02
Exponent Number: 1.101020e+03
