/ˌɪnt ˈθɜːrtiːˌtuː/
noun … “a signed 32-bit integer with a wide numeric range.”
INT32 is a fixed-width numeric data type that occupies exactly 32 bits of memory and can represent both negative and positive whole numbers. Using Two's Complement encoding, it provides a range from -2147483648 to 2147483647. The most significant bit is reserved for the sign, while the remaining 31 bits represent magnitude, enabling predictable arithmetic across the entire range.
Because of its larger size compared to INT16 or INT8, INT32 is often used in applications requiring high-precision counting, large arrays of numbers, timestamps, or memory addresses. Its fixed-width nature ensures consistent behavior across platforms and hardware architectures.
INT32 is closely related to other integer types such as UINT32, INT16, UINT16, INT8, and UINT8. Selecting INT32 allows programs to handle a broad numeric range while maintaining compatibility with lower-bit types in memory-efficient structures.
The intuition anchor is that INT32 is a large, predictable numeric container: four Bytes capable of holding very large positive and negative numbers without sacrificing deterministic behavior or arithmetic consistency.
