Other commentsː Kayan Busang (Uma:ʔ Tua:n) has a decimal system. The data was taken from Uma:ʔ Tua:n (one of the Kayan-Busa:ng subgroups among Kayanic peoples, in Long Tuyoq village, upper Mahakam, East Kalimantan, Indonesia in 1998. 
Note that the Kayanic peoples, the Uma:ʔ Tua:n and Uma:ʔ Lekan. They are called "Busa:ng" in Indonesia, while they are actually called "Kayan" in Sarawak (Malaysian Borneo). "Kayan" in general, or I prefer to call "Kayanic peoples," can be devided into 3 main subgroups, namely, Kayan-Busang, Bahau, and Ga'ay, according to their origins. The words of Uma:ʔ Tuaan are almost the same as some other Busa:ng / Kayan, such as the Uma:' Lekwee, Uma Mehak, Uma Wak, and Uma Luhat. On the other hand, the Uma:ʔ Lekan are slightly different from those Busa:ng of middle-upper Mahakam, and their language is closer to the Uma:ʔ Suling, etc.
Note that the traditional phonetic symbolsː  c=IPA [t͡ʃ],  j=IPA [dʒ], y=IPA [j]
