Int vs. Long: Know the Difference
By Shumaila Saeed || Published on February 2, 2024
Int is a data type for integers with a limited range, typically 32-bit, while Long is for larger integers, generally 64-bit, offering a broader range.
Key Differences
Int, short for integer, represents whole numbers in programming and typically occupies 32 bits in memory, limiting its range of values. Long, on the other hand, is an extended form of integer, generally occupying 64 bits, allowing for a much larger range of values. Both are used to store numerical data without decimal points but differ in their capacity.

In many programming languages, Int is the default data type for integer values due to its sufficient range for common tasks and efficient memory usage. Long is utilized when dealing with larger numbers that exceed Int's capacity, like in large-scale computations or handling big data. The choice between Int and Long depends on the required number range and memory considerations.

When programming, choosing between Int and Long also impacts performance. Int operations are generally faster and more memory-efficient, suitable for routine tasks. Long is used when these advantages are outweighed by the need for a larger numerical range, like in scientific calculations or financial applications.

In summary, Int and Long are both integral data types in computing, differing mainly in their size and range. Int is more common for everyday programming tasks, while Long is reserved for scenarios requiring handling of very large numbers.
