Python program to convert exponential to float

Last Updated : 23 Dec, 2020

Given a number in exponential format, the task is to write a Python program to convert the number from exponential format to float. The exponential number is a way of representing a number.

Examples:

Input: 1.900000e+01  Output: 19.0    Input: 2.002000e+03  Output: 2002.0    Input: 1.101020e+05  Output: 110102.0

Approach:

First, we will declare an exponential number and save it in a variable.
Then we will use the float() function to convert it to float datatype.
Then we will print the converted number.

Syntax:

float(x)

The float() method is used to return a floating-point number from a number or a string.

Example:

Python3

   # Python program to convert exponential to float 
  
# Declaring the exponential number 
exp_number = "{:e}".format(110102) 
  
# Converting it to float data type 
float_number = float(exp_number) 
  
# Printing the converted number 
print("Exponent Number:",exp_number) 
print("Float Number:",float_number)
 
  

Output:

Exponent Number: 1.101020e+05  Float Number: 110102.0
