## OverflowError: integer division result too large for a float#

The Python "OverflowError: integer division result too large for a float" occurs when the result of a division is too large. Use the floor division `//` operator to solve the error, e.g. `result = large_num // 5`. Here is an example of how the error occurs.

main.py
```Copied!```large_num = 5**1000

# ⛔️ OverflowError: integer division result too large for a float
result = large_num / 5
``````

The division operator `/` always produces a float value, however floating-point numbers always take the same amount of space.

To solve the error, we can use floor division `//`.

main.py
```Copied!```large_num = 5**1000

# ✅ using floor division
result = large_num // 5

print(result)
``````

Division `/` of integers yields a float, while floor division `//` of integers results in an integer.

The result of using the floor division operator is that of a mathematical division with the `floor()` function applied to the result.

Integers can store a variable amount of space as long as we have the required memory available.

A good way to illustrate the difference is to use the `sys.getsizeof()` method with integers and floats.

main.py
```Copied!```import sys

print(sys.getsizeof(1000))  # 👉️ 28
print(sys.getsizeof(10000000000))  # 👉️ 32

print(sys.getsizeof(3.0))  # 👉️ 24
print(sys.getsizeof(3.00000000000))  # 👉️ 24
``````

The sys.getsizeof method returns the size of an object in bytes.

Notice that the size of the integer grows with the number of digits, whereas floating-point numbers take the same amount of space regardless of how many digits the number consists of.

## Conclusion#

The Python "OverflowError: integer division result too large for a float" occurs when the result of a division is too large. Use the floor division `//` operator to solve the error, e.g. `result = large_num // 5`.
