täisarvutüüp

Täisarvutüüp refers to an integer data type in programming. It is a fundamental data type used to represent whole numbers, both positive and negative, as well as zero. Unlike floating-point types, integer types do not store fractional parts. The specific range of values that an integer type can hold depends on the programming language and the size of the integer (e.g., 8-bit, 16-bit, 32-bit, 64-bit).

Common integer types include signed integers, which can represent both positive and negative values, and unsigned integers, which can only represent non-negative values. The choice of integer type impacts the memory allocated for the variable and the range of numbers it can store. For example, a signed 32-bit integer typically ranges from -2,147,483,648 to 2,147,483,647, while an unsigned 32-bit integer ranges from 0 to 4,294,967,295.

Integer types are crucial for various programming tasks, such as counting, indexing arrays, and performing arithmetic operations where precision is not compromised by fractional values. When choosing an integer type, developers consider the expected range of values to prevent overflow errors, which occur when a calculation produces a result that exceeds the maximum value the type can hold.
