How to Round Floating Value to Two Decimals in Python

In this article, we will round off a float value in Python to the nearest two decimal places. Python provides us with multiple approaches to format numbers to 2 decimal places.

Get Two Decimal Places in Python

Below are some of the approaches by which we can get two decimal places in Python:

• Using round() Function
• String Formatting with % Operator
• Using f-strings

Round Floating Value to Two Decimals Using the round() Function

In this example, a floating-point number, 3.14159, is rounded to two decimal places using the round() Function.

Python3

number = 3.14159

# rounding the above number
rounded_number = round(number, 2)

print(rounded_number)  

Output

3.14

Round Floating Value to Two Decimals with % Operator

String formatting with the % operator allows us to control the presentation of a string or number. We can use string formatting with % operator to format a float value to two decimal places. Here we are using string formatting with % operator  to round the given value up to two decimals.

Python3

number = 3.14159

# Formatting the number to display two decimal places
formatted_number = "%.2f" % number

print(formatted_number) 

Output

3.14

Round Floating Value to Two Decimals Using f-strings

f-strings can be used to round off a float value to two decimal places. Here, we are using f-strings to round the given value up to two decimals.

Python3

number = 3.14159

formatted_number = f"{number:.2f}"

print(formatted_number) 

Output

3.14
