The field of floating-point computer arithmetic is a subsection of computer engineering that concentrates on the development and execution of arithmetic in microprocessors. The floating-point sections of processor chips and coprocessors are the units in a microprocessor that perform most of the arithmetic operations for applications such as 3D graphics, multimedia, signal processing, Fourier transforms, etc.
The floating-point format is a form of scientific notation. A floating-point number may represent a vast range of real numbers, with values ranging from nearly infinitely large to nearly infinitely small, all in a finite bit-width. Although many floating-point formats have been used, this chapter is based on the IEEE-754 Standard that is widely used at the current time.
