"WebSeveral different representations of real numbers have been proposed, but by far the most widely used is the floating-point representation.1Floating-point representations have a base (which is always assumed to be even) and a precision p. If = 10 and p= 3, then the number 0.1 is represented as 1.00 ×10-1. " - Floating point algorithm

WebThe floating-point emulation scheme discussed here is the block floating-point algorithm. The primary benefit of the block floating-point algorithm emanates from the fact that operations are carried out on a block basis using a common exponent. Here, each value in the block can be expressed in two components − a mantissa and a common exponent.
