Integer (computer science) In computer science, an integer is a datum of integral data type, a data type that represents some finite subset of the mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits (bits).
critical angle. Definition: The angle or greater, measured at the interface between a denser medium and a less dense in the same plane as the incident light, at which total internal reflection takes place - i.e. light is reflected back into the medium.
Definition of critical aperture - iDigitalPhoto Dictionary. Definition: The aperture setting which gives the best overall performance. * The relative aperture at which an optical system delivers the best balance between aberration correction and contrast rendition. Stop stopping down two. The commonest advice for using critical aperture was to stop down two stops from maximum: this continues to be useful for standard lenses of modest aperture and enlarging lenses, but not for other types.
