Functions
double	novas_dms_degrees (const char *restrict dms)
	Returns the decimal degrees for a DMS string specification.
double	novas_epoch (const char *restrict system)
	Returns the Julian day corresponding to an astronomical coordinate epoch.
double	novas_hms_hours (const char *restrict hms)
	Returns the decimal hours for a HMS string specification.
double	novas_parse_date (const char *restrict date, char **restrict tail)
	Parses an astronomical date/time string into a Julian date specification.
double	novas_parse_date_format (enum novas_calendar_type calendar, enum novas_date_format format, const char *restrict date, char **restrict tail)
	Parses a calendar date/time string, expressed in the specified type of calendar, into a Julian day (JD).
double	novas_parse_degrees (const char *restrict str, char **restrict tail)
	Parses an angle in degrees from a string that contains either a decimal degrees or else a broken-down DMS representation.
double	novas_parse_dms (const char *restrict dms, char **restrict tail)
	Parses the decimal degrees for a DMS string specification.
double	novas_parse_hms (const char *restrict hms, char **restrict tail)

double	novas_parse_hours (const char *restrict str, char **restrict tail)
	Parses a time or time-like angle from a string that contains either a decimal hours or else a broken-down HMS representation.
double	novas_parse_iso_date (const char *restrict date, char **restrict tail)
	Parses an ISO 8601 timestamp, converting it to a Julian day.
enum novas_timescale	novas_parse_timescale (const char *restrict str, char **restrict tail)
	Parses the timescale from a string containing a standard abbreviation (case insensitive), and returns the updated parse position after the timescale specification (if any).
double	novas_str_degrees (const char *restrict str)
	Returns an angle parsed from a string that contains either a decimal degrees or else a broken-down DMS representation.
double	novas_str_hours (const char *restrict str)
	Returns a time or time-like angleparsed from a string that contains either a decimal hours or else a broken-down HMS representation.
enum novas_timescale	novas_timescale_for_string (const char *restrict str)
