  2. Scale factor (computer science) - Wikipedia

    en.wikipedia.org/wiki/Scale_factor_(computer...

    [2] As an example of where precision is lost, a 16-bit unsigned integer (uint16) can only hold a value as large as 65,535 10. If unsigned 16-bit integers are used to represent values from 0 to 131,070 10, then a scale factor of 1 ⁄ 2 would be introduced, such that the scaled values correspond exactly to the real-world even integers.

  3. C data types - Wikipedia

    en.wikipedia.org/wiki/C_data_types

    Since C23, the language allows the programmer to define integers that have a width of an arbitrary number of bits. Those types are specified as _BitInt ( N ) , where N is an integer constant expression that denotes the number of bits, including the sign bit for signed types, represented in two's complement.

  4. Integer (computer science) - Wikipedia

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

    For example, if a programmer using the C language incorrectly declares as int a variable that will be used to store values greater than 2 15 −1, the program will fail on computers with 16-bit integers.

  5. Fixed-point arithmetic - Wikipedia

    en.wikipedia.org/wiki/Fixed-point_arithmetic

    A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor. For example, the value 1.23 can be stored in a variable as the integer value 1230 with implicit scaling factor of 1/1000 (meaning that the last 3 decimal digits are implicitly assumed to be a decimal fraction), and the value 1 230 000 can be represented ...

  6. Data type - Wikipedia

    en.wikipedia.org/wiki/Data_type

    The C programming language, for instance, supplies types such as Booleans, integers, floating-point numbers, etc., but the precise bit representations of these types are implementation-defined. The only C type with a precise machine representation is the char type that represents a byte.

  8. C mathematical functions - Wikipedia

    en.wikipedia.org/wiki/C_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. Most of these functions are also available in the C++ standard library, though in different headers (the C headers are included as well, but only as a deprecated compatibility feature).

  9. List of arbitrary-precision arithmetic software - Wikipedia

    en.wikipedia.org/wiki/List_of_arbitrary...

    Programming languages that support arbitrary precision computations, either built-in, or in the standard library of the language: Ada: the upcoming Ada 202x revision adds the Ada.Numerics.Big_Numbers.Big_Integers and Ada.Numerics.Big_Numbers.Big_Reals packages to the standard library, providing arbitrary precision integers and real numbers.
