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.

Here is the full code for reference:

import decimal x = decimal.Decimal(10.5) y = decimal.Decimal(2.5) z = x + y print(z) |
