Real-valued function
measured in grams is a function from this collection of weight to positive real numbers. The term "weight function", an allusion to this example, is used in pure and applied mathematics. In mathematics, a real-valued function is a function whose values are real numbers. In other words, it is a function that assigns a real number to each member of its domain. Real-valued functions of a real variable (commonly called real functions) and real-valued functions of several real variables are the main object of study of calculus and, more generally, real analysis. In particular, many function spaces consist of real-valued functions.
