Fixed Precision
In computing, fixed-point is a method of representing fraction (mathematics), fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. US dollar, Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cent (currency), cents (1/100 of dollar). More generally, the term may refer to representing fractional values as integer multiples of some fixed small unit, e.g. a fractional amount of hours as an integer multiple of ten-minute intervals. Fixed-point number representation is often contrasted to the more complicated and computationally demanding floating-point arithmetic, floating-point representation. In the fixed-point representation, the fraction is often expressed in the same radix, number base as the integer part, but using negative exponentiation, powers of the base ''b''. The most common variants are decimal (base 10) and binary number, binary (base 2). The latter is commonly known also as b ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. It includes the study and experimentation of algorithmic processes, and development of both hardware and software. Computing has scientific, engineering, mathematical, technological and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology and software engineering. The term "computing" is also synonymous with counting and calculating. In earlier times, it was used in reference to the action performed by mechanical computing machines, and before that, to human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. Computing is intimately tied to the representation of numbers, though mathematical conc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
