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.
A right angle is an angle that measures 90Ë. It is also known as a 'quarter turn' because it is a quarter of a full turn, which measures 360Ë. A right angle is represented by a small square inside the angle.An acute angle is one that measures LESS than 90Ë. An obtuse angle is one that measures between 90Ë and 180Ë.A reflex angle is an angle that measures between 180Ë and 360Ë.ook at the inside angles of this shape. Mark the acute angles in red, the obtuse angles in blue and the reflex angle in green.
