Can anyone please explain what happens, if "Digits" actually are "integers": FromDigits[{3,2}] 32(!) FromDigits[{13,2}] 132 (!!) FromDigits[{135,2}], 1352 (!!!) FromDigits[{1355078,9}] 13550789 (!!!!!!!) it's OK above, but: FromDigits[{135,21}] 1371 (??!!) FromDigits[{13,23}] 153 (??!!) FromDigits[{3,23}] 53 (??!!) And how to get integer 1323 from list {13,23}? So, or there is a better way: li={135,42};FromDigits[Flatten[{IntegerDigits[li[[1]]],IntegerDigits[li[[2]]]}]]-> 13542 Many thanks, and if you please send copy to seidovzf at yahoo.com Zak PS I use M4. M5 also gives FromDigits[{135,21}] 1371 (??!!)
