Two of the most common types to represent numeric values are int and float. The int type is used to represent a certain range of integers. The float type represents values with fractional parts. The latter requires more memory and also represents a wider range than the int type.
Remove Decimal Places in Python
In this article, we will discuss how to remove decimal places in Python. For this, we will convert the float values to an integer.
Using the int() function
The int() function is used to typecast a value to an integer. To remove decimal places in Python we will pass a float value with a decimal part to this function and it will remove decimal places in Python.
For example,
|
1 2 3 4 |
a =2.7 print(int(a)) |
Output
In the above example, we convert the float value to an integer and the decimal places are discarded.
Using the math library
The math library is used in Python to provide functions and constants that can calculate complex mathematical calculations. We can remove decimal places in Python using the truncate() function from the math library.
This function takes a float value and removes the decimal part from the same, returning the integer value.
See the code below.
|
1 2 3 4 5 |
import math a =2.7 print(math.trunc(a)) |
Output:
We can also use the floor() and ceil() functions from this library. The former function returns the largest integer smaller than the given number and the latter returns the smallest integer greater than the provided value.
It will round off the float value and return the calculated integer value.
For example,
|
1 2 3 4 5 6 |
import math a =2.7 print(math.floor(a)) print(math.ceil(a)) |

Using string formatting
String formatting refers to the technique of getting the output string in our desired format. Using the %d specifier we can get the output as an integer.
There are three ways in which we can use this format. The first method is by using the % formatting where we specify the format along with the variable.
See the code below.
|
1 2 3 4 |
a =2.7 print('%d'%a) |
Output:
Using the round() function
We can also use the round() function order to round the float value to the required integer and remove decimal places in Python.
See the code below.
|
1 2 3 4 |
a =2.7 print(round(a)) |
Please note that round() will remove decimal places, but it will also round the number to nearest integer.
Conclusion
To conclude this tutorial, we discussed several methods to remove decimal places in Python. For this, we converted the float type values to an integer using several methods. In the first method, we used the int function to typecast the float value. Then we used the round() function which rounded off the given value to the nearest integer.
We also demonstrated the use of functions from the math library. These were the trunc(), floor(), and ceil() functions. In the final method, we discussed how to use string formatting to remove decimal places in Python.
