How to Convert Numbers (from 1 to 99) to the Equivalent Arabic Ordinal Number String

Convert Numbers (from 1 to 99) to Arabic Ordinal Number String

Unlike English Ordinal Numbers where the ordinal number is made from the original number (in digital form) and a suffix is added to it (i.e. 1st, 2nd, 3rd, 4th......), the Arabic Ordinal Numbers cannot be written like that and an Arabic Ordinal Number is a full-text representation.

The table below lists selected Arabic Ordinal Numbers (from 1 to 99).

Arabic Ordinal Numbers differ if the subject is Masculine or Feminine.

There is no Javascript function or a solution on StackOverflow that can be found that can convert a number (in the range from 1 to 99) to the equivalent Arabic Ordinal Number text taking into account the type of the subject (Masculine or Feminine).

An example of such a function could be:

ordinalsAr(5);
ordinalsAr(21);

// result ==> الخامس
// result ==> الحادي والعشرون

ordinalsAr(5, true);   // true flag for Feminine
ordinalsAr(21, true);  // true flag for Feminine

// result ==> الخامسة
// result ==> الحادية والعشرون
