Python is a powerful programming language used for a wide range of applications such as web development, scientific computing, and more.
By default, Python can deal with integers, but if you want to work with decimals, you need to allow them in your code. This tutorial will show you how to allow decimals in Python.
Steps:
Step 1: Import the decimal module
To allow decimals in Python, you need to import the decimal module. This module provides support for decimal arithmetic. To import it, simply use the following code:
|
1 |
import decimal |
Step 2: Define a decimal
Once you have imported the decimal module, you can define a decimal in your code. To define a decimal, you need to use the Decimal class from the decimal module. Here is an example code:
|
1 |
x = decimal.Decimal(10.5) |
In this example, we have defined a variable x as a decimal with a value of 10.5. You can use any decimal value you want.
Step 3: Perform decimal arithmetic
Once you have defined a decimal, you can perform arithmetic operations on it just like you would with integers. Here is an example code:
|
1 2 3 4 |
x = decimal.Decimal(10.5) y = decimal.Decimal(2.5) z = x + y print(z) |
In this example, we have defined two variables x and y as decimals with values of 10.5 and 2.5 respectively. We then added them together and assigned the result to a third variable z. We then printed the value of z. The output will be:
Output:
13.0
Conclusion
In this tutorial, you learned how to allow decimals in Python by importing the decimal module, defining a decimal using the Decimal class, and performing arithmetic operations on decimals. With these skills, you can work with decimal values in your Python code.
