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.
Noun. 1. right angle-the 90 degree angle between two perpendicular lines. grad, grade-one-hundredth of a right angle. angle-the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians.oblique angle-an angle that is not a right angle or a multiple of a right angle.n. 1. (Mathematics) the angle between two radii of a circle that cut off on the circumference an arc equal in length to one quarter of the circumference; an angle of 90Â° or Ï/2 radians. 2. at right angles perpendicular or perpendicularly.ngle-the space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians. oblique angle-an angle that is not a right angle or a multiple of a right angle.
