WolframのIntegerDigitsをRに移植
IntegerDigits=\(n,b) n%/%b^(floor(log(n)/log(b)):0) %% b
> IntegerDigits(3^26,10)
[1] 2 5 4 1 8 6 5 8 2 8 3 2 9
> IntegerDigits(3^26,16)
[1] 2 4 15 13 3 0 2 7 15 14 9

In[1]:= IntegerDigits[3^26,10]
Out[1]= {2, 5, 4, 1, 8, 6, 5, 8, 2, 8, 3, 2, 9}
In[2]:= IntegerDigits[3^26,16]
Out[2]= {2, 4, 15, 13, 3, 0, 2, 7, 15, 14, 9}
17桁を越えるとRは間違える
