Sundanese numerals (Sundanese language: Wilangan) is a number system used by Sundanese people and contains a sequence of 10 digits (᮰᮱᮲᮳᮴᮵᮶᮷᮸᮹) in Sundanese script. The Wilangan writing system is the same as in Arabic numerals,[1] i.e. the writing is directed to the right,[1] only there is a difference in terms of marking, namely that the writing of numbers in Sundanese script must use a pipe sign ( | ),[1] because some forms of Sundanese numerals are similar to consonant letters (ᮍᮜᮌᮦᮔngalagéna), it is feared that ambiguity will occur.[2][1]
Example: || = 2020
However, because the writing system that is more often used in Sundanese is the Latin alphabet, it is more common to write numbers in Sundanese using Arabic numerals and the use of numbers in Sundanese script is optional.
Basic numbering in Sundanese
Some numbers in Sundanese have more than one different way of pronouncing the number, for example in the tweens, the way of pronouncing the numbers 21–29 can also use lilikuran.
