floating-point definition
<programming> A number representation consisting of a
mantissa, M, an exponent, E, and an (assumed) radix (or
"base") . The number represented is M*R^E where R is the
radix - usually ten but sometimes 2.
Many different representations are used for the mantissa and
exponent themselves. The IEEE specify a standard
representation which is used by many hardware floating-point
systems.
See also floating-point accelerator, floating-point unit.
Normalisation is the process of converting a floating point
number into canonical form where any number other than zero
has a mantissa whose first digit is non-zero.
Opposite: fixed-point.

floating-point accelerator definition
(FPA) Additional hardware to perform functions on
floating-point numbers such as addition, multiplication,
logarithms, exponentials, trigonometric functions and various
kinds of rounding and error detection. A floating-point
accelerator often functions as a co-processor to the CPU.
The term "floating-point accelerator" suggests a physically
larger system, often an extra circuit board, whereas a
"floating-point unit" is probably a single chip or even part
of a chip.
