- c - How big can a 64 bit unsigned integer be? - Stack Overflow
On a signed 64-bit integer, 2^64-1 is actually the number -1 If you use unsigned integers however, the value starts at 0 and 2^64-1 (18,446,744,073,709,551,615) becomes it's highest value, but unsigned integers cannot represent negative values
- Integer Limits | Microsoft Learn
If a value exceeds the largest integer representation, the Microsoft compiler generates an error
- INT_MAX and INT_MIN in C C++ and Applications - GeeksforGeeks
We usually assign a high value to the variable to compare and compute the minimum value in an array But if an array has large elements, we must assign the highest possible value to the variable ( i e INT_MAX )
- The largest number representable in 64 bits - GitHub Pages
That is indeed the maximum possible value of 64 bit unsigned integers, available as datatype uint64_t in C or u64 in Rust We can easily surpass this with floating point numbers
- 64 Bit Integer Limit: Understand It and Learn More!
The 64-bit integer limit refers to the maximum and minimum values a 64-bit number can hold For unsigned integers, the range is zero to 2^64 — 1, which equals 18446744073709551615
- What is the difference between int, Int16, Int32 and Int64?
Int64 (-9,223,372,036,854,775,808 to +9,223,372,036,854,775,807) or (−2^63 to +2^63−1) As stated by James Sutherland in his answer: int and Int32 are indeed synonymous; int will be a little more familiar looking, Int32 makes the 32-bitness more explicit to those reading your code
- Data Type Ranges | Microsoft Learn
The Microsoft C++ 32-bit and 64-bit compilers recognize the types in the table later in this article

Learn about the limits of 8, 16, 32, 64, and 128-bit integers in processors and data types with our 5-minute video lesson Test your knowledge with a quiz
- Demystifying 64-bit Long Integers and INT64_MAX in Linux C Programming
The INT64_MAX macro provides a handy way to document and validate that your variable or calculation requires the full 64-bit long integer range Here are some common use cases:
- c++ 64 Bit Int: Mastering Precision in Your Code
What is the maximum value of a 64-bit integer in C++? The maximum value of a 64-bit integer (specifically, `long long int` or `int64_t`) is 9,223,372,036,854,775,807
