  2. Type conversion - Wikipedia

    en.wikipedia.org/wiki/Type_conversion

    In these languages, conversion refers to either implicitly or explicitly changing a value from one data type storage format to another, e.g. a 16-bit integer to a 32-bit integer. The storage needs may change as a result of the conversion, including a possible loss of precision or truncation.

  3. LEB128 - Wikipedia

    en.wikipedia.org/wiki/LEB128

    The DWARF file format uses both unsigned and signed LEB128 encoding for various fields. [2] LLVM, in its Coverage Mapping Format [8] LLVM's implementation of LEB128 encoding and decoding is useful alongside the pseudocode above. [9].NET supports a "7-bit encoded int" format in the BinaryReader and BinaryWriter classes. [10]

  4. Variable-length quantity - Wikipedia

    en.wikipedia.org/wiki/Variable-length_quantity

    It is also used in the WAP environment, where it is called variable length unsigned integer or uintvar. The DWARF debugging format [ 4 ] defines a variant called LEB128 (or ULEB128 for unsigned numbers), where the least significant group of 7 bits is encoded in the first byte, and the most significant bits are in the last byte (so effectively ...

    CAG (file format) – Linear Reference System; FES (file format) – 3D Topicscape file, produced when a fileless occurrence in 3D Topicscape is exported to Windows. Used to permit round-trip (export Topicscape, change files and folders as desired, re-import them to 3D Topicscape) MGMF – MindGenius Mind Mapping Software file format

    en.wikipedia.org/wiki/Varchar

    Varchar fields can be of any size up to a limit, which varies by databases: an Oracle 11g database has a limit of 4000 bytes, [1] a MySQL 5.7 database has a limit of 65,535 bytes (for the entire row) [2] and Microsoft SQL Server 2008 has a limit of 8000 bytes (unless varchar(max) is used, which has a maximum storage capacity of 2 gigabytes).

  7. JavaScript syntax - Wikipedia

    en.wikipedia.org/wiki/JavaScript_syntax

    An Array is a JavaScript object prototyped from the Array constructor specifically designed to store data values indexed by integer keys. Arrays, unlike the basic Object type, are prototyped with methods and properties to aid the programmer in routine tasks (for example, join , slice , and push ).

  8. Data type - Wikipedia

    en.wikipedia.org/wiki/Data_type

    The standard type hierarchy of Python 3. In computer science and computer programming, a data type (or simply type) is a collection or grouping of data values, usually specified by a set of possible values, a set of allowed operations on these values, and/or a representation of these values as machine types. [1]

  9. UTF-8 - Wikipedia

    en.wikipedia.org/wiki/UTF-8

    It was designed for backward compatibility with ASCII: the first 128 characters of Unicode, which correspond one-to-one with ASCII, are encoded using a single byte with the same binary value as ASCII, so that a UTF-8-encoded file using only those characters is identical to an ASCII file.
