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: An angle whose measure is less than 90Â°. Try this Adjust the angle below by dragging an orange dot and see how the angle â ABC behaves. Note that it is acute for all angles from zero to (but not including) 90Â°. Acute angles are the smallest, being between (but not including) zero and 90Â° Note also that acute triangles are those where all the interior angles are acute. A way to remember Sometimes we can confuse acute and obtuse angles. A way to remember is that small things tend to be cute. Acute angle is the smallest type. Types of angle
