Extending The Real Numbers
The IEEE standard employs (and extends) the affinely extended real number system, with separate positive and negative infinities. During drafting, there was a proposal for the standard to incorporate the projectively extended real number system, with a single unsigned infinity, by providing programmers with a mode selection option. In the interest of reducing the complexity of the final standard, the projective mode was dropped, however. The Intel 8087 and Intel 80287 floating point co-processors both support this projective mode.

Famous quotes containing the words extending, real and/or numbers:
“In my experience, if you have to keep the lavatory door shut by extending your left leg, it’s modern architecture.”
—Nancy Banks-Smith, British columnist. Guardian (London, February 20, 1979)
“Talking about dreams is like talking about movies, since the cinema uses the language of dreams; years can pass in a second and you can hop from one place to another. It’s a language made of image. And in the real cinema, every object and every light means something, as in a dream.”
—Frederico Fellini (1920–1993)
“What culture lacks is the taste for anonymous, innumerable germination. Culture is smitten with counting and measuring; it feels out of place and uncomfortable with the innumerable; its efforts tend, on the contrary, to limit the numbers in all domains; it tries to count on its fingers.”
—Jean Dubuffet (1901–1985)
