Automated Small Telescope Remote Operation System: std angle format

The ASTROS standard angle format

We call the ASTROS standard angle format if the characters are written in one of the following 3 patterns.

for degree
value in degree with the character "d".
example 19.23d
for arcmin
value in degree with the character "d" and value in arcmin with the character "'".
example -20d3'
for arcsec
value in degree with the character "d" and value in arcmin with the character "'" and value in arcsec with the character """.
example 12d34'56.7"

The characters are case insensitive. Each value can be in an integer or a decimal fraction but not in a fraction. The plus or minus sign must be attached as the first character.
