getHour

public static String getHour(double rah)

Converts a double ra-h value into a xxhxxmxx.xs String.

Parameters:

rah -

Returns:

String

getDec

public static String getDec(double de)

Converts a double declination value into a xxdxx'xx.x" String.

getSexagesimal

public static String getSexagesimal(double ang,
                                    String d,
                                    String m,

                                    int digit)

Converts an angle into the sexagesimal format. This format uses integer degrees, followed by the degree-String, then integer arcminutes followed by the minute-String, then fractional seconds followed by the seconds-String. Any of these Strings can be empty.

Parameters:

angle - The angle to be converted into sexagesimal.

d - The degree-to-minute separator.

m - The minutes-to-seconds separator.

s - The String following the seconds.

digit - The number of digits in the seconds, zero for integer.

getSexagesimal

public static String getSexagesimal(double ang,
                                    String d,
                                    String m,
                                    String s,
                                    int digit,
                                    boolean full)

Converts an angle into the sexagesimal format. This format uses integer degrees, followed by the degree-String, then integer arcminutes followed by the minute-String, then fractional seconds followed by the seconds-String. Any of these Strings can be empty.

Parameters:

angle - The angle to be converted into sexagesimal.

d - The degree-to-minute separator.

m - The minutes-to-seconds separator.

s - The String following the seconds.

digit - The number of digits in the seconds, zero for integer.

full - If true, minutes and seconds are added even if zero.
