reaalväärtuslikud

Reaalväärtuslikud is an Estonian adjective that translates to "real-valued" in English. It is used in mathematics and related fields to describe quantities, functions, or variables that can take on any real number as their value. This contrasts with complex-valued quantities, which can include imaginary components, or discrete-valued quantities, which can only take specific, separate values.

In mathematics, a real-valued function, for example, is a function whose output is always a real number. Similarly, a real-valued variable is a variable that can represent any number within the set of real numbers. This set includes all rational numbers (like integers and fractions) and irrational numbers (like pi and the square root of 2). The concept of real-valued quantities is fundamental in calculus, analysis, and many areas of applied mathematics where measurements and continuous phenomena are modeled. The term emphasizes the nature of the output or possible values of a mathematical object, distinguishing it from other types of numbers or values.
