  3. 26-bit computing - Wikipedia

    en.wikipedia.org/wiki/26-bit_computing

    In computer architecture, 26-bit integers, memory addresses, or other data units are those that are 26 bits wide, and thus can represent unsigned values up to 67,108,863. . Two examples of computer processors that featured 26-bit memory addressing are certain second generation IBM System/370 mainframe computer models introduced in 1981 (and several subsequent models), which had 26-bit physical ...

  4. C mathematical functions - Wikipedia

    en.wikipedia.org/wiki/C_mathematical_functions

    C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. [1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions.

    en.wikipedia.org/wiki/Binary_multiplier

    A binary multiplier is an electronic circuit used in digital electronics, such as a computer, to multiply two binary numbers.. A variety of computer arithmetic techniques can be used to implement a digital multiplier.

    Add or subtract : 7.7 to 26 μs (floating point) Multiply : average 24 μs (24 bit precision fixed point) Multiply : 5 to 74 μs (floating point) Multiprocessing with Automatic Priority; The instruction format includes: [1] 7 bit op code; 2 bit real data indicator; 3 bit byte displacement; 3 bit mode selector; 1 sign bit; 8 bit 'byte activity'

  7. sizeof - Wikipedia

    en.wikipedia.org/wiki/Sizeof

    The printf width specifier z is intended to format that type. sizeof cannot be used in C preprocessor expressions, such as #if, because it is an element of the programming language, not of the preprocessor syntax, which has no data types. The following example in C++ uses the operator sizeof with variadic templates.

  8. Carry-less product - Wikipedia

    en.wikipedia.org/wiki/Carry-less_product

    Computing the carry-less product. The carry-less product of two binary numbers is the result of carry-less multiplication of these numbers. This operation conceptually works like long multiplication except for the fact that the carry is discarded instead of applied to the more significant position.

  9. Booth's multiplication algorithm - Wikipedia

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

    Booth's multiplication algorithm is a multiplication algorithm that multiplies two signed binary numbers in two's complement notation. The algorithm was invented by Andrew Donald Booth in 1950 while doing research on crystallography at Birkbeck College in Bloomsbury, London. [1] Booth's algorithm is of interest in the study of computer ...
