I'm working on memorizing 25 digits of π
The floor and ceiling functions give us the nearest integer up or down.
The floor and ceiling functions give us the nearest integer up or down.
21, 4, 0, and −2048 are integers, while 9.75, 5 1⁄2, and √2 are not.
ℕ or N means either { 0, 1, 2, 3, ...} or { 1, 2, 3, ...}.
edithe choice depends on the area of mathematics being studied; e.g. number theorists prefer the latter; analysts, set theorists and computer scientists prefer the former. To avoid confusion, always check an author's definition of N.
editℤ or ℤ means {..., −3, −2, −1, 0, 1, 2, 3, ...}.
editℤ+ or ℤ> means {1, 2, 3, ...} .
editℤ* or ℤ≥ means {0, 1, 2, 3, ...} .
editx ≤ y means x is less than or equal to y.
editx ≥ y means x is greater than or equal to y.
edit(The forms <= and >= are generally used in programming languages, where ease of typing and use of ASCII text is preferred.)

Featured Picture / Article Of The Day
editA planet is a large, rounded astronomical body that is neither a star nor a stellar remnant. The Solar System has eight (pictured): four terrestrial planets, Mercury, Venus, Earth and Mars; and four giant planets, Jupiter, Saturn, Uranus and Neptune. The term "planet" at first included the Sun, Moon and the five naked-eye planets that move across the background of the stars; they were seen as having associations with the gods. Copernicus theorized the Earth was a planet and, like the others, orbited the Sun. "Planet" came to include many objects, such as moons, within and beyond the Solar System. The International Astronomical Union in 2006 defined a planet in the Solar System to have cleared its neighborhood of other bodies, and that extrasolar planets should orbit stars and not be large enough to support deuterium fusion. Many planetary scientists, though, still apply the word "planet" more broadly, including dwarf planets, planetary-mass moons, rogue planets and brown dwarfs. (Full article...)
