AD 47 was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Claudius and Vitellius (or, less ...

There is a disagreement between astronomers and historians about how to count the years preceding year 1. In [Astronomical Algorithms], the 'B.C.' years are counted astronomically. Thus, the year before the year +1 is the year zero, and the year preceding the latter is the year −1. The year which historians call 585 B.C. is actually the year ...
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 ...
Densely packed decimal (DPD) is an efficient method for binary encoding decimal digits.. The traditional system of binary encoding for decimal digits, known as binary-coded decimal (BCD), uses four bits to encode each digit, resulting in significant wastage of binary data bandwidth (since four bits can store 16 states and are being used to store only 10), even when using packed BCD.
The list on the right shows the Fibonacci sequence: 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377. The 2, 8, and 9 resemble Arabic numerals more than Eastern Arabic numerals or Indian numerals . Leonardo Fibonacci was a Pisan mathematician who had studied in the Pisan trading colony of Bugia , in what is now Algeria , [ 15 ] and he ...
E.g. decimal 0.1 has the IEEE double representation 0 (1).1001 1001 1001 1001 1001 1001 1001 1001 1001 1001 1001 1001 1010 × 2^(-4); when added to 140737488355328.0 (which is 2 +47) it will lose all of its bits, except the first two. Thus from '= ( 140737488355328.0 + 0.1 - 140737488355328.0) it will come back as 0.09375 instead of 0.1 when ...
(The 8 × 3 = 24 non-standard encodings fill in the gap from 10 3 = 1000 and 2 10 - 1 = 1023. Benefit of this encoding is access to individual digits by de- / encoding only 10 bits, disadvantage is that some simple functions like sort and compare, very frequently used in coding, do not work on the bit pattern but require decoding to decimal ...
