OverflowError: int Too Large to Convert

Why This Happens

Python integers have arbitrary precision but floats are limited to ~1.8e308. Converting very large integers to float raises OverflowError.

The Problem

big = 10 ** 1000
result = float(big)

The Fix

from decimal import Decimal
big = 10 ** 1000
result = Decimal(big)

# Or integer arithmetic:
result = big // 3

Step-by-Step Fix

1. 1

   Use Decimal

   Use decimal.Decimal for very large number arithmetic.

2. 2

   Use integer arithmetic

   Use // for division without float conversion.

3. 3

   Use logarithms

   Compare large numbers by their logarithms.
