  2. Recycling codes - Wikipedia

    en.wikipedia.org/wiki/Recycling_codes

    Recycling codes on products. Recycling codes are used to identify the materials out of which the item is made, to facilitate easier recycling process.The presence on an item of a recycling code, a chasing arrows logo, or a resin code, is not an automatic indicator that a material is recyclable; it is an explanation of what the item is made of.

    the usual weights assigned to the bit positions are 0-1-2-3-6. However, in this scheme, zero is encoded as binary 01100; strictly speaking the 0-1-2-3-6 previously claimed is just a mnemonic device. [2] The weights give a unique encoding for most digits, but allow two encodings for 3: 0+3 or 10010 and 1+2 or 01100.

  4. Densely packed decimal - Wikipedia

    en.wikipedia.org/wiki/Densely_packed_decimal

    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.

  5. Route distinguisher - Wikipedia

    en.wikipedia.org/wiki/Route_distinguisher

    The route distinguisher (RD) is an 8-octet value consisting of two major fields, the Type Field (2 octets) and Value Field (6 octets). The type field determines how the value field should be interpreted. The three Type values, as defined in the Internet draft, are: Type 0:

  6. BCD (character encoding) - Wikipedia

    en.wikipedia.org/wiki/BCD_(character_encoding)

    BCD (binary-coded decimal), also called alphanumeric BCD, alphameric BCD, BCD Interchange Code, [1] or BCDIC, [1] is a family of representations of numerals, uppercase Latin letters, and some special and control characters as six-bit character codes. Unlike later encodings such as ASCII, BCD codes were not standardized. Different computer ...

    In versions of Windows prior to Windows Vista, the default configuration of the Recycle Bin is a global setting for all drives to hold 10% of the total capacity of each host hard drive volume to store deleted files. For example, on a volume with a capacity of 20 gigabytes, the Recycle Bin will hold up to 2 gigabytes of deleted files.

  8. Bit numbering - Wikipedia

    en.wikipedia.org/wiki/Bit_numbering

    This table illustrates an example of an 8 bit signed decimal value using the two's complement method. The MSb most significant bit has a negative weight in signed integers, in this case -2 7 = -128. The other bits have positive weights. The lsb (least significant bit) has weight 1. The signed value is in this case -128+2 = -126.

  9. HP-16C - Wikipedia

    The original firmware still had a bug where numbers whose hexadecimal representation ends in E or F are displayed incorrectly in decimal mode, which was fixed by a community effort in October 2023. Several emulators , including official by HP, are available for desktop computers, web browsers, smartphones and other calculators.
