Are you having problems figuring out how to round a float to two decimals in Python? Don’t worry about it! This article will outline the problem’s causes and suggest possible fixes. Let’s get going!
The way to round a float to 2 decimals in python?
Firstly, we need to understand what is a float value and how to round it to 2 decimals:
Fundamental floating point values are also referred to as floats. A decimal point separates the integer and fractional components of floating-point numbers.
For instance: 7.29, 10.24
Method 1: Utilize Python round()
The round() method’s floating point number is the number’s spherical equivalent in decimal form. Take a look at the syntax of round() method:
The parameter of it will be:
Number: Essential. The amount to round
Digits: Elective. The amount of decimals to round the number. The default is zero.
As you can see, the rounded number is the first parameter. The second option controls how many decimal places are rounded. Provide the second argument as 2, rounding the number to two decimal places. The final digit is raised by one of the third digits following the decimal point that exceeds 5.
Apply the syntax in the script. We will have the command below:
# for integers print(round(10)) # for floating point print(round(10.7,2)) print(round(5.5678,2)) print(round(-12.481,2))
10 10.7 5.57 -12.48
Method 2: Utilize format()
We can use the str.format() function to show a float value with two decimal places. It is easy to implement and maintains real value. The syntax of this is:
Apply that to Python. We will have the script as:
myFloat = 23.98765; print(format(myFloat, '.2f'));
The output will be:
Although this strategy is not typically used for rounding to two decimals, you should be cautious and carefully consider what will be the best approach in your circumstance.
