Max value of integer

4    Asked by aj_6299 in Java , Asked on Apr 1, 2025

Ever wondered what the maximum value an integer can hold in different programming languages? How does it vary between 32-bit and 64-bit systems? Let’s explore the limits of integer values!

Answered by Ajit yadav

The maximum value of an integer depends on the programming language and system architecture (32-bit vs. 64-bit). Here’s a breakdown of integer limits in some common languages:

1. Integer Limits in Popular Languages

C/C++

int (typically 32-bit): 2,147,483,647 (2^31 - 1)

long long (64-bit): 9,223,372,036,854,775,807 (2^63 - 1)

Java

int: 2,147,483,647 (Integer.MAX_VALUE)

long: 9,223,372,036,854,775,807 (Long.MAX_VALUE)

Python

No fixed max value! Python’s int type supports arbitrary precision, meaning it can grow as long as memory allows.

JavaScript

Number.MAX_SAFE_INTEGER: 9,007,199,254,740,991 (for safe integer operations)

BigInt: No fixed limit, similar to Python’s int.

2. Why Do Integer Limits Matter?

  • Overflow Issues – Exceeding the max value can cause unexpected behavior in some languages.
  • Performance Considerations – Larger numbers consume more memory and processing power.
  • Choosing the Right Type – Always select a data type that fits your needs without wasting resources.

If you’re working with numbers beyond these limits, consider using BigInt (JavaScript), BigInteger (Java), or arbitrary precision integers (Python).
