  2. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    In C, unsigned integer overflow is defined to wrap around, while signed integer overflow causes undefined behavior. ... Python 2 — convert to long type (bigint)

  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. Sign extension - Wikipedia

    en.wikipedia.org/wiki/Sign_extension

    If the source of the operation is an unsigned number, then zero extension is usually the correct way to move it to a larger field while preserving its numeric value, while sign extension is correct for signed numbers. In the x86 and x64 instruction sets, the movzx instruction ("move with zero extension") performs this function.

  5. Primitive data type - Wikipedia

    en.wikipedia.org/wiki/Primitive_data_type

    Minimally, there are four types, char, int, float, and double, but the qualifiers short, long, signed, and unsigned mean that C contains numerous target-dependent integer and floating-point primitive types. [15]

  6. Comparison of programming languages (basic instructions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    In C and C++ short, long, and long long types are required to be at least 16, 32, and 64 bits wide, respectively, but can be more. The int type is required to be at least as wide as short and at most as wide as long , and is typically the width of the word size on the processor of the machine (i.e. on a 32-bit machine it is often 32 bits wide ...

  7. Integer (computer science) - Wikipedia

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

    This type is not supported by compilers that require C code to be compliant with the previous C++ standard, C++03, because the long long type did not exist in C++03. For an ANSI/ISO compliant compiler, the minimum requirements for the specified ranges, that is, −(2 63 −1) [ 11 ] to 2 63 −1 for signed and 0 to 2 64 −1 for unsigned, [ 12 ...

  8. Single-precision floating-point format - Wikipedia

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

    Here we can show how to convert a base-10 real number into an IEEE 754 binary32 format using the following outline: Consider a real number with an integer and a fraction part such as 12.375; Convert and normalize the integer part into binary; Convert the fraction part using the following technique as shown here

  9. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    The C language provides the four basic arithmetic type specifiers char, int, float and double (as well as the boolean type bool), and the modifiers signed, unsigned, short, and long.
