The [[IEEE 754-2008]] standard includes an encoding format for decimal floating point numbers in which the significand and the exponent (and the payloads of [[NaN]]s) can be encoded in two ways, referred to in the draft as binary encoding and decimal encoding.<ref>{{cite web

Line 16 ⟶ 17:
Both formats break a number down into a sign bit ''s'', an exponent ''q'' (between ''q''<sub>min</sub> and ''q''<sub>max</sub>), and a ''p''-digit significand ''c'' (between 0 and 10<sup>''p''</sup>−1). The value encoded is (−1)<sup>''s''</sup>×10<sup>''q''</sup>×''c''. In both formats the range of possible values is identical, but they differ in how the significand ''c'' is represented. In the decimal encoding, it is encoded as a series of ''p'' decimal digits (using the [[densely packed decimal]] encoding. This makes conversion to decimal form efficient, but requires a specialized decimal [[ALU]] to process. In the '''binary integer decimal''' encoding, it is encoded as a binary number.
