Expression for angle

SYNOPSIS

[+|-][degd][arcmin[m|M|']][arcsec[s/S/"]]
[+|-][hourh][minm][secs]
[+|-]radianrad
If the first part is with "d" or "h", the followin "m" and "s" are automatically adjust in "arc" or "time". The time is, of cause, used for the right acsension, that is 1h = 15deg.

DESTCRIPTION

The astonomonical software often uses values in angle. There is no universal rulte to express the angle in a single word. In STAR/ULTRA system most of commands use the following expression for angles.
The values accept floating point and no upperlimit, say 60.0. The sign must be attached as the first character.

EXSAMPLE

-12d34m56s --> -45296.0 arcsec = -12.582222 degree
 12d34'56" -->  45296.0 arcsec =  12.582222 degrees
 34'56"    -->   2096.0 arcsec =   0.582222 degrees
-34M56S    -->  -2096.0 arcsec =  -0.582222 degrees
 12h30m    --> 675000.0 arcsec = 187.5 degrees
 30m15s    -->  27225.0 arcsec =   7.5625 degrees
 1.0rad    -->  57.297 degrees

-0d30m     --> -0.5  degrees
-10d-30m   --> -10.5 degrees
 10d-30m   --> -10.5 degrees

 12.5d      --> 12.5 degrees
 12.5d10.2s --> 45010.2 arcsec = 12.502833 degrees
