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 numberfloat_number = 1101.02# Converting the float number to exponential numberexp_number = "{:e}".format(float_number)# Printing the converted numberprint("Float Number:",float_number)print("Exponent Number:",exp_number) |
Output:
Float Number: 1101.02 Exponent Number: 1.101020e+03
