floating-point coding compaction
Data compaction accomplished by using coefficients, a base, and exponents to specify the scale, range, or magnitude of numbers. Note: An example of floating-point coding compaction is using 119.8 × 106, 119.8(6), or 119.86 to represent 119,800,000. If the number is rounded to 120,000,000, it might be written as 1206 or 127 in which the last digit is the number of zeros to be appended to the preceding digits. Thus, only three positions are required instead of nine to represent the number in storage or in a message, which is only 33% of the original space and time requirement. [From Weik '89]
