Floating-point unit
A
floating-point unit
(
FPU
, colloquially a
math coprocessor
) is a part of a
computer
system specially designed to carry out operations on
floating point
numbers. Typical operations are
addition
,
subtraction
,
multiplication
,
division
,
square root
, and
bitshifting
. Some systems (particularly older,
microcode
-based architectures) can also perform various
transcendental functions
such as
exponential
or
trigonometric
calculations, though in most modern processors these are done with software library routines.
