  2. Comparison of C Sharp and Java - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_C_Sharp_and_Java

    [21] [22] [23] Contrary to the float and double data types, decimal fractional numbers such as 0.1 can be represented exactly in the decimal representation. In the float and double representations, such numbers often have non-terminating binary expansions, making those representations more prone to round-off errors. [22]

  3. Comparison of data-serialization formats - Wikipedia

    PER Aligned: a fixed number of bits if the integer type has a finite range and the size of the range is less than 65536; a variable number of octets otherwise; OER: 1, 2, or 4 octets (either signed or unsigned) if the integer type has a finite range that fits in that number of octets; a variable number of octets otherwise

  4. C Sharp (programming language) - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_(programming_language)

    Examples of value types are all primitive types, such as int (a signed 32-bit integer), float (a 32-bit IEEE floating-point number), char (a 16-bit Unicode code unit), decimal (fixed-point numbers useful for handling currency amounts), and System. DateTime (identifies a specific point in time with nanosecond precision).

  5. C Sharp syntax - Wikipedia

    en.wikipedia.org/wiki/C_Sharp_syntax

    This is a feature of C# 9.0. Similar to in scripting languages, top-level statements removes the ceremony of having to declare the Program class with a Main method. Instead, statements can be written directly in one specific file, and that file will be the entry point of the program. Code in other files will still have to be defined in classes.

  6. Comparison of programming languages (basic instructions)

    Integers, floating point numbers, strings, etc. are all considered "scalars". ^e PHP has two arbitrary-precision libraries. The BCMath library just uses strings as datatype.

  7. Computer number format - Wikipedia

    en.wikipedia.org/wiki/Computer_number_format

    To approximate the greater range and precision of real numbers, we have to abandon signed integers and fixed-point numbers and go to a "floating-point" format. In the decimal system, we are familiar with floating-point numbers of the form (scientific notation): 1.1030402 × 10 5 = 1.1030402 × 100000 = 110304.02. or, more compactly: 1.1030402E5

  8. Value type and reference type - Wikipedia

    en.wikipedia.org/wiki/Value_type_and_reference_type

    Java [4] all non-object types, including (e.g.) booleans and numbers: all object types, including (e.g.) arrays C++: all data types, except reference types, array types and function types: arrays and functions C# [5] all non-object types, including structures and enumerations as well as primitive types: all object-types, including both classes ...

  9. 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. Double precision may be chosen when the range or precision of single precision would be insufficient.
