6 unusual facts about Binary-coded decimal


Binary-coded decimal

Fixed-point decimal numbers are supported by some programming languages (such as COBOL and PL/I).

Denser packings of BCD exist which avoid the storage penalty and also need no arithmetic operations for common conversions.

Some languages (such as COBOL and PL/I) directly support fixed-point zoned decimal values, assigning an implicit decimal point at some location between the decimal digits of a number.

Packed BCD is supported in the COBOL programming language as the "COMPUTATIONAL-3" (an IBM extension adopted by many other compiler vendors) or "PACKED-DECIMAL" (part of the 1985 COBOL standard) data type.

In the 1972 case Gottschalk v. Benson, the U.S. Supreme Court overturned a lower court decision which had allowed a patent for converting BCD encoded numbers to binary on a computer.

Carbon planet

In August 2011, Matthew Bailes and his team of experts from Swinburne University of Technology in Australia reported that the millisecond pulsar PSR J1719-1438 may have a binary companion star that has been crushed into a much smaller planet made largely of solid diamond.

Cochran test

Extended SMTP

Prior to the availability of 8BITMIME implementations, mail user agents employed several techniques to cope with the seven-bit limitation, such as binary-to-text encodings (including ones provided by MIME) and UTF-7.

Factorial code

Jürgen Schmidhuber (1992) re-formulated the problem in terms of predictors and binary feature detectors, each receiving the raw data as an input.

To create factorial codes, Horace Barlow and co-workers suggested to minimize the sum of the bit entropies of the code components of binary codes (1989).

The IMP-16 was later superseded by National Semiconductor's PACE and INS8900 single-chip 16-bit microprocessors, which had a similar architecture but were not binary compatible.

Mensch Computer

Much software originally written for other computer systems which use the 65816 or 6502 instruction sets (such as the Nintendo Entertainment System, Super Nintendo, or Apple IIgs, among others) can be run on the Mensch Computer (either directly as binary object code or through reassembling the software source code), to the extent that such software does not rely on hardware configurations which differ from the Mensch Computer.

In computing, Microsoft Binary Format (MBF) was a format for floating point numbers used in Microsoft's BASIC language products including MBASIC, QuickBasic and GW-BASIC.

Mizar and Alcor

More components of the Mizar system were discovered with the advent of the telescope and spectroscopy; a fine, easily-split visual target, Mizar was the first telescopic binary discovered—most probably by Benedetto Castelli who in 1617 asked Galileo Galilei to observe it.

N-ary code

A prefix that indicates an integer, e.g., "bin", "tern," or "quatern", may be used in lieu of a numeral, to produce "binary", "ternary", or "quaternary" (2, 3, and 4 states respectively).
