  2. 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.

  3. Weighted correlation network analysis - Wikipedia

    en.wikipedia.org/wiki/Weighted_correlation...

    As the unsigned measure , the signed similarity takes on a value between 0 and 1. Note that the unsigned similarity between two oppositely expressed genes ((,) =) equals 1 while it equals 0 for the signed similarity. Similarly, while the unsigned co-expression measure of two genes with zero correlation remains zero, the signed similarity equals ...

  4. Primitive data type - Wikipedia

    en.wikipedia.org/wiki/Primitive_data_type

    The set of basic C data types is similar to Java's. 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]

  5. Signedness - Wikipedia

    en.wikipedia.org/wiki/Signedness

    For Integers, the unsigned modifier defines the type to be unsigned. The default integer signedness outside bit-fields is signed, but can be set explicitly with signed modifier. By contrast, the C standard declares signed char, unsigned char, and char, to be three distinct types, but specifies that all three must have the same size and alignment.

  6. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    All C integer types have signed and unsigned variants. If signed or unsigned is not specified explicitly, in most circumstances, signed is assumed. However, for historic reasons, plain char is a type distinct from both signed char and unsigned char. It may be a signed type or an unsigned type, depending on the compiler and the character set (C ...

  7. Compatibility of C and C++ - Wikipedia

    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    Therefore, true and false have type int in C. This is likely to change in C23 however, whose draft includes changing bool, true, and false to become keywords, and giving true and false the type bool. In C it is implementation-defined whether a bit field of type int is signed or unsigned while in C++ it is always signed to match the underlying type.

  8. Type punning - Wikipedia

    en.wikipedia.org/wiki/Type_punning

    In addition to the assumption about bit-representation of floating-point numbers, the above floating-point type-punning example also violates the C language's constraints on how objects are accessed: [3] the declared type of x is float but it is read through an expression of type unsigned int.

  9. 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 ...
