Täisarvmuutuja

Täisarvmuutuja is an Estonian term that translates to "integer variable" in English. It refers to a variable that can hold only whole numbers, meaning numbers without any fractional or decimal component. In programming and mathematics, integer variables are fundamental data types used to represent quantities that are inherently discrete. Examples of integer values include -3, 0, 15, and 1000. They cannot represent values like 3.14 or -0.5.

The range of values an integer variable can hold is typically determined by the specific programming language or system being used. Some systems might offer different types of integer variables, such as short integers or long integers, to accommodate a wider or narrower spectrum of whole numbers. This distinction is important for memory management and to prevent overflow errors, where a calculation results in a number too large to be stored by the variable. Integer variables are commonly used for counting, indexing arrays, and performing arithmetic operations where only whole number results are meaningful.
