In the next section, you’ll learn how to use string methods to truncate a float in Python. We can see here that the same result is returned as when using the int() function. Let’s see how we can use the trunc() function to truncate some numbers in Python: # Truncate a float in Python with un() While it may seem trivial to use another library to do this, it can help your code read a little clearer to explain what the function is doing and why it’s doing it.īecause our intention is to truncate a float, the trunc() function makes this explicitly clear, whereas the int() function doesn’t. Similar to the int() function, the math library has a library that can be helpful to truncate a float in Python, the trunc() function. Use the Math Library to Truncate a Float in Python Want to learn how to use the Python zip() function to iterate over two lists? This tutorial teaches you exactly what the zip() function does and shows you some creative ways to use the function. In the next section, you’ll learn how to use the math library to truncate a float in Python. We can see here that anything following the decimal place is truncated. Let’s see how we can use the int() function to truncate a float in Python: # Truncate a float in Python with int() It’s also different from the floor(), which returns an integer now greater than a number. This is differently than the round() function, as it does not round up. The function only removes anything following the decimal, regardless of what follows it. The int() function works differently than the round() and floor() function (which you can learn more about here). The built-in int() function takes a float and converts it to an integer, thereby truncating a float value by removing its decimal places. Use the int Function to Truncate a Float in Python
