Excess-3, 3-excess [1] [2] [3] or 10-excess-3 binary code (often abbreviated as XS-3, [4] 3XS [1] or X3 [5] [6]), shifted binary [7] or Stibitz code [1] [2] [8] [9] (after George Stibitz, [10] who built a relay-based adding machine in 1937 [11] [12]) is a self-complementary binary-coded decimal (BCD) code and numeral system. It is a biased ...
The IEEE 754 floating-point standard defines the exponent field of a single-precision (32-bit) number as an 8-bit excess-127 field. The double-precision (64-bit) exponent field is an 11-bit excess-1023 field; see exponent bias. It also had use for binary-coded decimal numbers as excess-3.
Offset binary, [1] also referred to as excess-K, [1] excess-N, excess-e, [2] [3] excess code or biased representation, is a method for signed number representation where a signed number n is represented by the bit pattern corresponding to the unsigned number n+K, K being the biasing value or offset.
This scheme can also be referred to as Simple Binary-Coded Decimal (SBCD) or BCD 8421, and is the most common encoding. [12] Others include the so-called "4221" and "7421" encoding – named after the weighting used for the bits – and "Excess-3". [13]

If a subsection of a specific codevalue is extracted from that value, for example the last 3 bits of a 4-bit Gray code, the resulting code will be an "excess Gray code". This code shows the property of counting backwards in those extracted bits if the original value is further increased.
