# Python program to convert exponential to float

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```
