IMAGINARY NUMBER [10 records]

Record 1 2016-09-14

English

Subject field(s)
  • Mathematics
CONT

Complex numbers have real and imaginary parts. However, if a number has no real part, then it is called "pure imaginary. "

  • Computer Mathematics
DEF

A real or imaginary number expressed as a+bi where a and bi are real numbers and i is the square root of-1.

French

Domaine(s)
  • Mathématiques
  • Mathématiques informatiques
DEF

Groupe de deux nombres dont un est réel et l'autre imaginaire, qui correspond à un point dans le plan complexe.

CONT

Le nombre complexe correspond à des points.

OBS

Le plan complexe contient une infinité non dénombrable de ces points; la partie réelle comme la partie imaginaire de chacun peuvent être positives ou négatives, entières ou non entières.

DEF

Combinación de un número real y de un número imaginario en forma de (a + bi).

OBS

El número a la izquierda del par es la «parte real» del número complejo, mientras que la parte de la derecha es la parte puramente imaginaria del número complejo.

Record 4 1999-01-27

Subject field(s)
  • Information Theory
DEF

In FORTRAN, an ordered pair of real constants separated by a comma and enclosed in parentheses. The first real constant represents the real part of the complex number; the second represents the imaginary part.

Record 5 1998-05-13

English

Subject field(s)
  • Analytical Chemistry
DEF

In gas chromatography, the theory that the column operated similarly to a distillation column; for example, chromatographic columns are considered as consisting of a number of theoretical plates, each performing a partial separation of components.

OBS

The plate concept of chromatography is inherited from distillation theory, where originally the more efficient distillation columns actually contained discrete plates. Martin and Synge considered a chromatographic system to be composed of a number of imaginary or theoretical plates. However, the number of theoretical plates that a column appears to contain is a poor measure of chromatographic performance since the number of plates is independent of the system dimensions.

PHR

discrete plate

Record 6 1994-08-31

English

Subject field(s)
  • Computer Mathematics
DEF

A generalized complex number that is the sum of a real number and a vector and that depends on one real and three imaginary units the third of which is the product of the first two and also the negative of this product when the order of the factors is reversed so that multiplication over the fields of quaternions is not commutative.

French

Domaine(s)
  • Mathématiques informatiques
DEF

Nombre complexe quadridimensionnel constitué de quatre nombres scalaires pris dans un ordre déterminé, et combinés selon certaines lois.

OBS

Premier exemple d'un corps non commutatif, les quaternions forment une extension quadridimensionnelle du plan complexe. Le produit de deux quaternions normés et un quaternion normé.

PHR

Record 7 1994-07-08

English

Subject field(s)
  • Computer Graphics
  • Mathematics
CONT

A number is complex when it is made up of two parts, which are called real and imaginary. These terms no longer have any special significance : the two parts of a complex number might as well be called Humpty and Dumpty. Thus 7 + 4i is a complex number with real part 7(Humpty) and imaginary part 4i(Dumpty). The i next to the 4 shows which part of the complex number is imaginary. Every complex number can be represented by a point in the plane; the plane of complex numbers is called the complex plane... The complex plane is an unaccountable infinity of such numbers. Their real parts and their inspima parts can be either positive or negative and either whole numbers or decimal expansions.

English

Subject field(s)
  • Computer Hardware
DEF

The area directly addressable as a Cartesian coordinate grid. The number space can be considered to have an imaginary grid overlayed on it. The number space may be equivalent to the dynamic range and/or viewing area. If the number space is greater than the CRT screen, the beam is scissored at the CRT edges. Wrap around usually occurs at the four edges of the number area.
