Classes
struct	toy::_divmod10

Namespaces
namespace	toy
	Root namespace containing all engine modules.

Functions
constexpr _divmod10	toy::_divModU10 (uint32_t value) noexcept
	Divides a given 32-bit unsigned integer by 10 and returns the quotient and remainder.
constexpr int32_t	toy::_ftoa32Engine (char *buffer, float value, size_t precision) noexcept
	Converts a floating-point number to its string representation in a specified precision.
constexpr int32_t	toy::_ftoa64Engine (char *buffer, double value, size_t precision) noexcept
	Converts a 64-bit floating-point number to its string representation with specified precision.
void	toy::_floatPostProcess (char *dest, char *srcBuffer, size_t bufferSize, int32_t exp10, size_t precision) noexcept
	Processes a string representation of a floating-point number, adjusting the exponent, and stripping trailing zeros.
wchar_t *	toy::utf8toWChar (wchar_t *dest, size_t destSize, const char *src, size_t count) noexcept
	Converts a UTF-8 C string to a wide-character string with a character count limit.
char *	toy::wcharToUtf8 (char *dest, size_t destSize, const wchar_t *src) noexcept
	Converts a wide-character C string to UTF-8.
size_t	toy::utf8Len (const char *string) noexcept
	Returns the number of Unicode code points in a UTF-8 encoded C string.
char *	toy::ftoa (char *dest, size_t destSize, float value, size_t precision=7) noexcept
	Converts a float to its decimal C string representation with specified precision.
char *	toy::ftoa (char *dest, size_t destSize, double value, size_t precision=15) noexcept
	Converts a double to its decimal C string representation with specified precision.
void	toy::formatNumberString (char *buffer, size_t bufferSize, const char *separator) noexcept
	Inserts a grouping separator into a number C string every three digits from the right.

Variables
static constexpr array< uint8_t, 256 >	toy::_utf8CharSizeTable
	UTF-8 character size lookup table for efficient UTF-8 parsing.
constexpr array< uint32_t, 32 >	toy::_exponentTable
	Precomputed exponent lookup table for efficient binary-to-decimal floating-point conversion.
constexpr size_t	toy::_decimalDigitsPerGroup = 3
	Number of decimal digits per group when formatNumberString() inserts the caller-supplied separator.
