Any number that is not an integer but is very close to one
Ed Pegg Jr. noted that the length d equals , which is very close to 7 (7.0000000857 ca.)[1]
In recreational mathematics, an almost integer (or near-integer) is any number that is not an integer but is very close to one. Almost integers may be considered interesting when they arise in some context in which they are unexpected.
