(Astronomical Numerals)
Set-I ( )
Here, the Abjad letters have been mentioned which have numeric values from 1 to 9. The right side of image describes the way these letters are mentioned as numerical constants in Raqm-Nujoomi while the left side shows the corresponding letter in their general representative format. One may mark that the letter د Dāl is written similar to hamzah ء while Jeem ج is written half without its dot and hā ح is written as it is. Zaa ز ag*in doesn't have its dot in the representation. There is a similar case with Bā ب.
Set-II ( )
Here, in the second image, letters having numeric values 10, 20, 30, 40, 50, 60, 70, 80 and 90 have been represented in both the general and Abjad formats. Ag*in, some letters such as Nūn ن are written in a different way while Seen س, Ayn ع and Sawd ص are written half (or with small haa like end as in Urdu, e.g. عہ is ع) as shown in the second image. Numbers ranging between two letters in this range such as between 10 and 20 are represented by the combinations of the first two sets of Abjad letters. For example, if one has to write 34 then the representation will be as follows, 34 = 30 + 4, Lām (ل) 30 + Dāl 4 (د) ,Thus, 34 is لد.
set-III ( and )
The final set of Abjad is being described in the third image, these letters are although not frequently used in Astronomical calculations as the hours, minutes and seconds vary in the range of 1 to 60 while angles are dealt generally in the range 0 to 90 (and upto 180 for longitudes) or at max upto 360 degrees.
: In Raqm-Nujoomi, the come first then the then the and then the (from right to left as we write in Urdu/Arabic) غثسه is thus 1,565.
