The natural domain of a formula is the set of values for which it is defined, typically within the reals but sometimes among the integers or complex numbers. For instance the natural domain of square root is the non-negative reals when considered as a real number function. When considering a natural domain the set of possible values of the function is typically called its range.

Famous quotes containing the words natural and/or domain:
“This letter will be delivered to you by my child,—the child of my adoption,—my affection! Unblest with one natural friend, she merits a thousand. I send her to you innocent as an angel, and artless as purity itself; and I send you with her the heart of your friend, the only hope he has on earth, the subject of his tenderest thoughts, and the object of his latest cares.”
—Frances Burney (1752–1840)
“Without metaphor the handling of general concepts such as culture and civilization becomes impossible, and that of disease and disorder is the obvious one for the case in point. Is not crisis itself a concept we owe to Hippocrates? In the social and cultural domain no metaphor is more apt than the pathological one.”
—Johan Huizinga (1872–1945)
