The floating point unit is a dedicated execution unit designed for performing math functions on floating point numbers. A floating point number is any number other than an integer; any number with a decimal point required to represent it is a floating point number.

Floating point - Wikipedia, the free encyclopedia
In computing, floating point describes a system for numerical representation in which a string of digits (or bits) represents a rational number. The term floating point refers to the fact that the...

A floating point unit (FPU), also known as a math coprocessor or numeric coprocessor, is a specialized coprocessor that manipulates numbers more quickly than the basic microprocessor circuitry. The FPU does this by means of instructions that focus entirely on large mathematical operations. ... This can, in many cases,

Such programs uses less space (fixed-point subroutine libraries are far smaller than floating-point libaries, especially when just one or two routines are put into the system). On microprocessors without a floating-point unit, the fixed-point version of a program usually runs faster than floating-point version.

We describe the design, implementation, and evaluation of a dual-issue SIMD-like extension of the PowerPC 440 floating-point unit (FPU) core. This extended FPU is targeted at both IBM's massively parallel Blue-Gene/L machine as well as more pervasive embedded platforms. ... Antibes Juan-les-Pins, France ... September 29-October 03...

The floating point unit of the next generation PowerPC is detailed. It has been tested at over 5 GHz. The design supports an extremely aggressive cycle time of 13 FO4 using a technology independent measure. For most dependent instructions, its fused multiply-add dataflow has only 6 effective pipeline stages.
