Binary angular measurement
From Wikipedia, the free encyclopedia
Binary angular measurement (BAM)[1] (and the binary angular measurement system, BAMS[2]) is a measure of angles using binary numbers and fixed-point arithmetic, in which a full turn is represented by the value 1. The unit of angular measure used in those methods may be called binary radian (brad) or binary degree.
These representation of angles are often used in numerical control and digital signal processing applications, such as robotics, navigation,[3] computer games,[4] and digital sensors,[5] taking advantage of the implicit modular reduction achieved by truncating binary numbers. It may also be used as the fractional part of a fixed-point number counting the number of full rotations of e.g. a vehicle's wheels or a leadscrew.
