  3. Integer (computer science) - Wikipedia

    en.wikipedia.org/wiki/Integer_(computer_science)

    Programmers may also incorrectly assume that a pointer can be converted to an integer without loss of information, which may work on (some) 32-bit computers, but fail on 64-bit computers with 64-bit pointers and 32-bit integers. This issue is resolved by C99 in stdint.h in the form of intptr_t.

  4. 64-bit computing - Wikipedia

    en.wikipedia.org/wiki/64-bit_computing

    On systems with 64-bit processors, both the 32- and 64-bit macOS kernels can run 32-bit user-mode code, and all versions of macOS up to macOS Mojave (10.14) include 32-bit versions of libraries that 32-bit applications would use, so 32-bit user-mode software for macOS will run on those systems.

    As with Cygwin, MSYS2 supports path translation for non-MSYS2 software launched from it. For example one can use the command notepad++ /c/Users/John/file.txt to launch an editor that will open the file with the Windows path C:\Users\John\file.txt. [9] [8] MSYS2 and its bash environment is used by Git and GNU Octave for their official Windows ...

  6. Double-precision floating-point format - Wikipedia

    en.wikipedia.org/wiki/Double-precision_floating...

    Double-precision floating-point format (sometimes called FP64 or float64) is a floating-point number format, usually occupying 64 bits in computer memory; it represents a wide range of numeric values by using a floating radix point.

  7. LEB128 - Wikipedia

    en.wikipedia.org/wiki/LEB128

    .NET supports a "7-bit encoded int" format in the BinaryReader and BinaryWriter classes. [10] When writing a string to a BinaryWriter, the string length is encoded with this method. Minecraft uses LEB128 in its protocol for measuring lengths of data within packets. [11] The mpatrol debugging tool uses LEB128 in its tracing file format. [12]

  8. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with. This allows great flexibility: for example, all types can be 64-bit.

  9. Windows Runtime - Wikipedia

    en.wikipedia.org/wiki/Windows_Runtime

    Windows Phone 8.1 uses a version of the Windows Runtime named the Windows Phone Runtime. It enables developing applications in C# and VB.NET, and Windows Runtime components in C++/CX. [32] Although WP8 brought limited support, the platform did eventually converge with Windows 8.1 in Windows Phone 8.1.
