Every programming language has a limit to how large an integer can be.
This is because there is a set number of bits that can be used to represent a number, and so those bits only have so many different permutations.
Typically, when this number is exceeded, the number is called an overflow, and will go negative if the number is signed.
In Python 2, the maximum value for an integer is limited to 2 ** 63 - 1.
That is to say the number 2, raised to the power of 63, minus 1.
In Python 3, the maximum value is determined by the machine that the code is running on.
In this post, we'll learn how to get the maximum value for an integer in Python at runtime.
The easiest way to get the maximum value for an integer is to use the built-in function
sys functions, you need to import the
import sys print (sys.maxint)
Keep in mind that as mentioned before, this is the maximum value for an integer in Python 2.
For Python 3, this doesn't apply because the value is unbounded, determined by the machine running the code.
In this post, we saw how to get the maximum value for an integer in Python at runtime when on Python 2.
This is different on Python 3 which just relies on the under-lying system to determine the maximum value.
Hopefully, this has been helpful to you. Thanks for reading!
