  2. 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 ...

  3. Signed number representations - Wikipedia

    en.wikipedia.org/wiki/Signed_number_representations

    Addition of a pair of two's-complement integers is the same as addition of a pair of unsigned numbers (except for detection of overflow, if that is done); the same is true for subtraction and even for N lowest significant bits of a product (value of multiplication). For instance, a two's-complement addition of 127 and −128 gives the same ...

  4. 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]

  5. Division algorithm - Wikipedia

    en.wikipedia.org/wiki/Division_algorithm

    The following algorithm, the binary version of the famous long division, will divide N by D, placing the quotient in Q and the remainder in R. In the following pseudo-code, all values are treated as unsigned integers.

  6. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    For unsigned integers, the bitwise complement of a number is the "mirror reflection" of the number across the half-way point of the unsigned integer's range. For example, for 8-bit unsigned integers, NOT x = 255 - x , which can be visualized on a graph as a downward line that effectively "flips" an increasing range from 0 to 255, to a ...

  7. Binary multiplier - Wikipedia

    en.wikipedia.org/wiki/Binary_multiplier

    For example, suppose we want to multiply two unsigned 8-bit integers together: a[7:0] and b[7:0]. We can produce eight partial products by performing eight 1-bit multiplications, one for each bit in multiplicand a:

  8. Integer overflow - Wikipedia

    en.wikipedia.org/wiki/Integer_overflow

    modulo power of two (char is the only unsigned primitive type in Java) modulo power of two JavaScript: all numbers are double-precision floating-point except the new BigInt: MATLAB: Builtin integers saturate. Fixed-point integers configurable to wrap or saturate Python 2 — convert to long type (bigint) Seed7 — raise OVERFLOW_ERROR [11 ...

  9. Booth's multiplication algorithm - Wikipedia

    en.wikipedia.org/wiki/Booth's_multiplication...

    Booth's algorithm can be implemented by repeatedly adding (with ordinary unsigned binary addition) one of two predetermined values A and S to a product P, then performing a rightward arithmetic shift on P. Let m and r be the multiplicand and multiplier, respectively; and let x and y represent the number of bits in m and r.
