Python setting Decimal Place range without rounding

In Python, you can control the decimal places of a floating-point number without rounding it by using the decimal module. This module provides a Decimal data type that allows you to specify the exact precision you want for your numbers. In this tutorial, we will show you how to set a decimal place range without rounding using the decimal module with code examples.
The decimal module in Python allows you to perform fixed-point and floating-point arithmetic with arbitrary precision. You can specify the number of decimal places you want, and the module will handle the precision without rounding.
To use the decimal module, you first need to import it:
We also import getcontext to access the context settings for the Decimal module.
You can set the precision for Decimal numbers using the getcontext().prec attribute. Here's how you can set the precision to a specific number of decimal places:
In this example, we set the precision to 10 decimal places, but you can adjust this value according to your needs.
Now that you've set the precision, you can perform arithmetic operations without worrying about rounding. Here are some examples:
As you can see, the results maintain the specified precision without rounding.
If you want to convert the Decimal number to a string with a specific precision, you can use the quantize method. This method rounds the number to the specified precision:
In this example, we rounded result to two decimal places.
Using the decimal module in Python, you can set the decimal place range without rounding, making it suitable for financial calculations or any situation where you need precise decimal arithmetic. Remember to adjust the precision setting to match your specific requirements.
