In this post, we will learn How to Limit float to two decimal points where we can use the round () function and where we can provide the variable and the number of decimal points we want as the argument of the function.
Limit the Decimal points In Float Values
Using Round Method
As we know we can use the round() built in function to get the round up the value and get the precise value where we provide the variable and the number of decimal points we want and the function will return the digit which we want and in the form we want with limited decimal points.
number = 3.14159 rounded_ number = round( number, 2) print( rounded_ number)
And the above example of pseudo code will result in 3.14 as it will limit the decimal points up to two points only as we had provided the limit as two in the code above.
Using String Formatting
We can also limit the decimal values by using string formatting and even by f-string which is only possible in the latest versions as 3.6 and above. For the same, we have given the example below for each method so let’s look at the examples.
number = 3.14159
formatted_ number = "{:.2f}".format( number)
print( formatted_ number)
here we have used formatting to get the limited decimals points so by limiting the decimals points and here the result will be the same as 3.14 which was the same as it was in the case of the around method so for the same way we can also implement another method too which is f- strings.
Using f-strings
We have given the example below to implement the same which will also result in the same result.
number = 3.14159
formatted_ number = f"{ number:.2f}"
print( formatted_ number)
Using the Decimal Module
We can also use another method by as importing the decimal module and here we have given an example to implement the same which we can directly execute.
from decimal import Decimal
number = Decimal('3.14159')
rounded_ number = round( number, 2)
print( rounded_ number)
Here also the above code will result in 3.14 only as we have provided the argument as 2 for the execution.
