Ordinal number(day) variable

[Dimitrije]

Could we get a variable that outputs ordinal numbers, specifically days of the month, in the correct format: 1st, 2nd, 3rd etc? I hope it's a simple addition but would help tremendously for certain captions. I suggest the name {dord}

As a quick fix, you could define code replacements, e.g.
o1 1st
o2 2nd
o3 3rd
...
and then use $o{iday}$
