Add st, nd, rd and th (ordinal) suffix to a number
...he expression ((n + 90) % 100 - 10) % 10 - 1 does the mapping. Breaking it down:
(n + 90) % 100: This expression takes the input integer − 10 mod 100, mapping 10 to 0, ... 99 to 89, 0 to 90, ..., 9 to 99. Now the integers ending in 11, 12, 13 are at the lower end (mapped to 1, 2, 3).
