Abstract
A high-speed method for the compression and decompression of floating point numbers. The floating point numbers are biased using a predefined value and then stored in compressed format occupying less memory than that of the non-compressed floating point numbers. Decompression of the compressed floating point number follows a reverse process. These techniques are useful with applications in which the numbers to be compressed fall within a given range.
