Decimal floating point (3 or 4 binary bits), and the rest of the significand uses the densely packed decimal (DPD) encoding. Unlike the binary integer significand version, where the exponent changed position and came before the significand, this encoding combines the leading 2 bits of the exponent and the leading digit (3 or 4 bits) of the significand into the five bits that follow the sign bit. This is followed by a fixed-offset exponent continuation field. Finally, the significand continuation field made of 2, 5, or 11 10-bit "declets", each encoding 3 decimal digits. If the first two bits after the sign bit
Point and figure chart subject. A detailed history can be found in Jeremy du Plessis’ ‘The Definitive Guide to Point and Figure’ where many references and examples are cited. Du Plessis describes the historical development of these charts from a price recording system to a charting method. Traders kept track of prices by writing them down in columns. They noticed patterns in their price record and started referring to them first as ‘fluctuation charts’ and then as ‘figure charts’. They started using Xs instead of numbers and these charts became known as ‘point charts’. Traders used both point charts and figure charts together and
