Definition
Noun: A system for representing numbers in which the position of the radix point (decimal point, binary point, etc.) is predetermined and fixed. This contrasts with floating-point notation, where the point's position can vary.
Usage
This term is used primarily in computing, mathematics, and digital electronics to describe a specific method of numerical representation. It is often discussed in contrast to floating-point representation.
Examples
- Noun:
- The early digital calculator used fixed-point notation for all its arithmetic operations.
- For applications where speed is critical and the range of numbers is known, fixed-point notation can be more efficient than floating-point.
Advanced Usage
- "to be in fixed-point notation": Describes data or a value that is encoded using this system.
- The sensor data is stored in fixed-point notation to simplify the processing algorithm.
Variants and Related Words
- Fixed-point arithmetic (n): The branch of computer arithmetic concerning calculations performed on numbers in fixed-point notation.
- The digital signal processor is optimized for fixed-point arithmetic.
Synonyms
- Fixed-point representation: A direct synonym.
- Fixed-point number system: A synonym emphasizing the system aspect.
Antonyms
- Floating-point notation: A numeration system where the position of the radix point is not fixed but is indicated by an exponent.
Noun
- a radix numeration system in which the location of the decimal point is fixed by convention
