How to Fix “TypeError: ‘Float’ Object Cannot be Interpreted as an Integer” in Python?

Did you pass a float value to a function that expects an int value and get the TypeError: ‘Float’ Object Cannot be Interpreted as an Integer in Python?

In Python, we’ve two data types, integers, and floats, that represent numbers, both of these have distinct properties. Some functions support integers, floats, or both, but functions like range() only support an integer value; otherwise, we’ll get the “TypeError: ‘Float’ Object Cannot be Interpreted as an Integer” error.

In this article, we’ll discuss the “TypeError: ‘float’ object cannot be interpreted as an integer” error in Python, why it occurs, and how to fix it. So without further ado, let’s dive deep into the topic:

Why Does the “TypeError: ‘Float’ Object Cannot be Interpreted as an Integer” Error Occurs?

As we’ve discussed in Python, some functions just expect integer values, and providing otherwise values like floats causes TypeError: ‘float’ object cannot be interpreted as an integer. Let’s see an example 👇:

Code

num = 100

new_num = num / 10



print("New number is ",new_num)



# loop 

for i in range(new_num):

    print(i)

Output

See the above example; the range() function expects an integer value, whereas the provided value is a float. Let’s see the data type of it.

Code

num = 100

new_num = num / 10



print(f"The data type of {num} is {type(num)}")

print(f"The data type of {new_num} is {type(new_num)}")

Output

The data type of 100 is <class 'int'> The data type of 10.0 is <class 'float'>

As we have seen in the above example, the data types of variables num and new_num are int and float, and the float data type caused the TypeError: ‘float’ object cannot be interpreted as an integer.

How to Fix the “TypeError: ‘Float’ Object Cannot be Interpreted as an Integer” Error in Python?

To fix the error float object cannot be interpreted as an integer; we have three different alternate solutions.

1. Floor division
2. Typecasting
3. Exception handling

1. Floor Division

Floor division is a division operator where the quotient returned by this operator depends on the argument being passed to it. And if any of the numbers is float, it returns float; otherwise integer. It is also known as floor division because the result is automatically floored; let’s see an example:

Code

num = 100

a = num / 10 # simple division

b = num // 10 # floor division

print(f"The data type of {a} is {type(a)} ")

print(f"The data type of {b} is {type(b)} ")

Output

The data type of 10.0 is <class 'float'> 

The data type of 10 is <class 'int'>

Floor division gives an integer value; as a result, the float value is rounded off after division to the nearest value.

2. Typecasting

Typecasting is a type conversion approach that helps in converting the data type of a variable or object from one to another. Let’s an example to demonstrate the concept of typecasting:

Code

num = 50

new_num = num / 10 



print(f"The data type of {new_num} is {type(new_num)}")



# typecast new_num from 'float' to 'int'

new_num = int(new_num)

print(f"\nThe data type of {new_num} after typecasting is {type(new_num)}\n")



for i in range(new_num):

    print(i)

Output

The data type of 5.0 is <class 'float'>

The data type of 5 after typecasting is <class 'int'>

3. Exception handling

Exception handling is a common but most useful feature of any programming language that helps us handle exceptions before they crash our programs. Let’s see an example.

Code

try:

    num = 100

    new_num = num / 10

    

    for i in range(new_num):

        print(i)

        

except TypeError:

    # customize message

    print("TypeError: range doesn't support float values")
    

print("This program isn't crashed yet!")

Output

TypeError: range doesn't support float values

This program isn't crashed yet!
