In this tutorial, learn how to limit float to two decimal places in Python. The short answer is: use the Python format() and round() to convert float to two decimal places.
If you want to make calculations using Python programming in Two decimals places. You have to use the changed or limit the float value to two decimal places. Because the float value can be more than two decimal and its difficult to make calculations.
So, What are the different methods for limiting float to two decimal places in Python? Read this post to the end to learn how to restrict the number to two decimal places.
Limit Float to Two Decimal Places Using Format() Function
To limit the float value to the two decimal places, you have to use the
There are two arguments in the format function. The first argument is the float variable that you want to convert to two decimal places. The second argument is
'.2f' showing to convert to two decimal places.
myFloat = 10.887555;
The above example showing the output with two decimal places. It may increase the second decimal place to one more. If the digit after it is 5 or more than 5.
You can also convert or restrict the number to 2 decimal place using the round function. To learn the conversion, you have to read the next section of the post with round().
How to RountFloat to 2 Decimal Places Using Round()
If you want to restrict number to 2 decimal places, you have to use the
round() of Python.
Round function requires two arguments to pass for the conversion. The first argument is the float variable whose value you want to change or limit. The second argument is the number of decimal places you want to convert to.
Round function is the common function to make the float value in required round figure.
myFloat = 10.887555;
The above example showing the changes or converted a float value to two decimal places.
Both the function format() and round() convert the float value to two decimal places. You can use any of them in your python programming as per your requirement.
