How to round a value to two decimal places in Python ? That’s a very good question. Lucky for you, Python offers some functions that allow you to round numbers.

Rounding of numbers to two decimal places is common. Money only uses two decimal places; you don’t want to treat a monetary value with a third decimal place. Weights are often represented with two decimal places; the extra values ‚Äã‚Äãare for extra precision that is not needed in most cases.

In this guide, we explain how to round a number to two decimal places in Python. Let’s take a look at two code snippets to help you learn how to round numbers in your code.

Rounding off numbers using round ()

We need to write a program that calculates how much money each friend in a group of friends has to pay for dinner. It starts by asking the user to enter how much a meal costs and how many friends were there:

Then we calculate how much each friend has to pay for dinner. We assume that each friend should pay an equal amount, no matter what they ordered:

We converted both "meal_cost" and "friends" to a floating point number . Indeed, the input () method returns a string. You cannot do a calculation on a string value using Python mathematical operators.

Now let’s round this value to two decimal places. We use the round () method. The round () method. turns a value to the nearest integer or to the nearest decimal

We also print the amount each friend must contribute to the console dinner:

We used the built-in round () to round the value of "cost_per_friend" to two decimal places. Next, we used the string concatenation to create a message to print to the console. This post teaches us how much each friend has to pay for their dinner

Run our code to see our working function .

If we had divided 64.92 by six without rounding the number, we would have seen a number with multiple decimal places. Our code calculates that each friend owes pay $ 10.82 for dinner by rounding the of our division sum to two decimal places. <

h2> Round off numbers using the string formatting

In our last example, we showed the rounded number in a string. There is another way to round a number if its only purpose is to be displayed in a string. This method is only supported in Python 3.x.

Let’s revise our code to round off the value each friend has to pay for dinner using the .format () syntax of formatting strings .

Let’s start by calculating how much each friend has to pay:

Then , write a print () statement that tells us how much each friend has to pay for dinner. We use a .format () instruction with the print () instruction. This allows us to format the values within our string:

Our .format () statement uses the following syntax to create a decimal representation of a number rounded to two places:

A colon (: ) tells our code that we want to format a value. The zero is used to let Python know that we are dealing with a number that can be padded with zeros. The .2 tells Python to round our number to two decimal places. The "f" shows our value as a number

Let’s run our code and see what happens:

Our code successfully calculates how much each friend has to pay for dinner. The result is like our first code snippet. There are two decimal places that show our numeric data has been rounded to two decimal places.

This method is more efficient than our first code snippet because all we want to do is print a value to the console. In this code, we haven’t used a round () statement.

If we were to use our rounded value further in our code, the string formatting syntax would not be practical

Conclusion

the most common approach . to round a value to two decimal places are:

The first method is valid for all cases where you need to round a number. The second method only works if you want to round a value to use in a string and if you are using Python 3.x.

You are now ready to round values ‚Äã‚Äãto two decimal places in your code like Python pro !
