In this post, we will look at the intricacies of the “OverflowError” problem. The maximum limit for each data type is set in Python. The value must be within the data type limit before you perform any mathematical calculations. If the value is too large, the data type will not accommodate it. Python generates an error in this scenario, noting that the value exceeds the permitted limit. In this circumstance, the developer should take appropriate action in response to the interest. We will look at how to deal with such situations in this article. We go over all of the different solutions to this problem. Python uses operands when performing mathematical computations. The operands are any of the python data types’ variables. The defined data types can be stored up to their maximum limit in the variable. If the application tries to store a value that exceeds the data type’s maximum limit, python may throw an error declaring that the permissible limit has been exceeded. We will look at different instances that cause the Math

## Example 1:

This issue can be recreated using the exp python math operation. The maximum number of data types that can be used is 709.78271. The python program will display an error if the program simulates a value that exceeds the allowable limit.

output=math.exp(1000)

print(output)

The above raised the error, as you can see.

## Example 2:

We can see in this program’s code that we are declaring the math module, after that, using it to generate exponential numbers like exp(1000), where x is 1000 while e is 2.7, and when we try to calculate this, it delivers us a value as a result that is double, and it cannot print the result. As can be seen in the following program, an overflow error occurs, indicating that the value is out of range because the given value is 1000 and the outcome is out of range.

import math

print("Here is the exponential value:")

print(math.exp(1000))

As you can see, the above code caused the Math range error.

## Example 3:

The phrase “Result too large” does not refer to the number of characters in the decimal representation of the number; rather, it signifies that the number produced by your exponential function is large enough to overrun whatever type Python employs to store floating-point values internally. Floats in Python are neither arbitrary precision nor limitless in size. x = x ** 2 is far too huge when I = 10. Either use an alternative type for your floating-point computations, such as decimal module: d = decimal.Decimal(x ** 2), or modify your code such that e**(x) does not overflow or underflow.

for i in range(50):

a = a ** 2

print(a)

The following is an example of an OverflowError.

## Solution 1:

As previously stated, the value should not surpass the maximum data type limit. The difficulty can be solved by calculating the exponential value with less. Before the exponential operation is performed, an if condition is used to validate the input value. The caller will receive the proper error message if the input value is higher than 0. The code below demonstrates how to utilize the exponential function without causing a program error.

num = 80

if num<50:

output=math.exp(num)

print(output)

else:

print("The input value exceeds the permitted limit.")

The above code is successfully performed without causing any errors, as shown below.

## Solution 2:

If the input value is unreliable, the error can be handled using the try-except construct. Add the appropriate code for the execution of the program to the try block. If an error occurs, recognize it and choose an alternative course of action. In this method, the code will handle the overflow exception. The code below demonstrates how to use try and except to handle an overflow error in a Python program.

try:

result =math.exp(1000)

except OverflowError:

result = float('inf')

print(result)

Below is the result.

## Conclusion:

An overflow error happens when the current runtime value retrieved by the Python application exceeds the limit value, as discussed in this article. This issue arises when we apply arithmetic operations in the program, and the outcome exceeds the maximum range value, as we saw in this post. When converting from one data type to another, this error occurs when the value exceeds the storage range of the chosen data type. Finally, we showed how to handle this issue using the try and except blocks to manage exceptions.
