An **integer-valued function** is a function whose outputs are always integers. This means that for every input value from its domain, the corresponding output value is an integer. Formally, if \\( f: A \\rightarrow \\mathbb\{Z\} \\), where \\( A \\) is a set (the domain of the function), and \\( \\mathbb\{Z\} \\) is the set of all integers, then \\( f \\) is an integer-valued function.
