Classes
class	xtd::bit_converter
	Converts base data types to an std::vector of bytes, and an std::vector of bytes to base data types. More...
class	xtd::console
	Represents the standard input, output, and error streams for console applications. More...
class	xtd::convert
	Represents API to convert base type code. More...
class	xtd::convert_pointer
	Represents API to convert pointers. More...
class	xtd::convert_string
	Represents API to convert string containers. More...
class	xtd::environment
	The environment class. More...
struct	xtd::guid
	Represents a globally unique identifier (GUID). A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated. More...
class	xtd::math
	Provides constants and static methods for trigonometric, logarithmic, and other common mathematical functions. More...
class	xtd::random
	Represents a pseudo-random number generator, a device that produces a sequence of numbers that meet certain statistical requirements for randomness. More...
class	xtd::translator
	Represents translator class. This class cannot be inherited. More...
class	xtd::ustring
	Represents text as a sequence of UTF-8 code units. More...
class	xtd::version
	Represents the version number of an assembly, operating system, or the xtd. This class cannot be inherited. More...
