string	to_roman (int32_t nr)
	Generates a Roman numeral string for an integer.
string	to_Roman (int32_t nr)
	Generates an uppercase Roman numeral string for an integer.
string	hanzi_sub (int16_t nr, bool leading_zero)
string	to_hanzi (int32_t nr)
	Generates a Chinese numeral for a given integer.
string	to_padded_Hex (uint8_t i)
string	to_padded_hex (uint8_t i)
	Converts an 8-bit unsigned integer to a fixed-length (2) hex string.
template<typename T >
std::enable_if_t< std::conjunction_v< std::is_integral< T >, std::is_unsigned< T > >, void >	to_Hex_positive (T i, string &s)
	Handle positive number separately to avoid unnecessary check of sign. string is passed into the function as reference, thus no reference counting is performed.
string	to_Hex (int32_t i)
string	to_hex (int32_t i)
string	to_Hex (pointer ptr)
string	to_hex (pointer ptr)
	Converts a pointer to a hexadecimal string.
int	from_hex (string s)
	Converts a hexadecimal string to an integer.
template<unsigned int cur, typename T >
std::enable_if_t< std::conjunction_v< std::is_integral< T >, std::is_unsigned< T > >, void >	as_hexadecimal_sub (T i, string &s)
	Handle positive number separately to avoid unnecessary check of sign. string is passed into the function as reference, thus no reference counting is performed. Because length of string s is known here, use index instead of appending operator can avoid cost of reallocation. Firstly a string of given length is constructed, then digits is filled according to index rather than appending to the tail.
string	as_hexadecimal (int i, int length)
	Converts an unsigned integer to a hexadecimal string with a fixed length.
string	uint32_to_Hex (uint32_t i)
	Converts an unsigned integer to a hexadecimal string.
string	binary_to_hexadecimal (string bin)
	Converts a binary stream to its hexadecimal represention.
string	to_hex (int i)
	Converts an integer to a hexadecimal string.

std::enable_if_t< std::conjunction_v< std::is_integral< T >, std::is_unsigned< T > >, void > lolly::data::as_hexadecimal_sub	(	T	i,

Handle positive number separately to avoid unnecessary check of sign. string is passed into the function as reference, thus no reference counting is performed. Because length of string s is known here, use index instead of appending operator can avoid cost of reallocation. Firstly a string of given length is constructed, then digits is filled according to index rather than appending to the tail.

Template Parameters

T	unsigned integral type is expected.
