How To Make Python Not Round

Sometimes when working with Python, you may need to display a decimal number without rounding it off. In this tutorial, we will show you how to make Python not round your numbers.


Step 1: Import Decimal Module

To work with decimal numbers in Python, you will need to import the decimal module. You can do this using the following line of code:

Step 2: Use Decimal Module to Specify Precision

Once you have imported the decimal module, you can use it to set the precision level of your decimal numbers.

The precision level determines the number of digits to the right of the decimal point. To set the precision level, you can use the decimal.getcontext() method, which returns a DecimalContext object that you can use to specify the precision level like this:

In this example, we have set the precision level to 5, which means that any decimal number we work with will have a maximum of 5 digits to the right of the decimal point.

Step 3: Create a Decimal Object

To create a decimal object, you can use the Decimal() function provided by the decimal module. This function takes a string or a number as an argument and returns a decimal object. Here is an example:

This code creates a decimal object with a value of 3.14159.

Step 4: Display Decimal Object

To display the decimal object without rounding it off, you can simply print it as you would with any other variable in Python. For example:

This will display the value of the decimal object with the precision level you specified in Step 2.


By using the decimal module and setting the precision level, you can make Python display decimal numbers without rounding them off. This is useful when you need to work with precise decimal numbers in your Python programs.
