ask yourself what numeric types it makes sense to convert the values you describe
Why wouldn't it make sense? If b >= 10, you obviously have to define 'digits' for 10+; using A-Z for 10-36 is quite common. Equally obvious: The result of conversion must be treated as a digit string; there is no other way to handle, say, a base 13 number in a binary computer.

In decimal, the digits to the left of the decimal point give the number of ones, then number of tens, then ten**2s, ten**3s, ten**4s, ... To the right of the decimal point digits give the number of 1/10s, then the number of 1/(10**2)s, 1/(10**3)s, 1/(10**4)s, ...

For base b, the digits to the left of the point give the number of ones, then number of bs, then b**2s, b**3s, b**4s, ... To the right of the point, digits give the number of 1/bs, then the number of 1/(b**2)s, 1/(b**3)s, 1/(b**4)s, ...

I guess it would be somewhat confusing to call it a decimal point, though.

"Octal is just like decimal ... if you are missing two fingers" (Tom Lehrer)

To the OP: I would have split the number on the point, treating the whole and the fractional parts separately, converting then to binary integers, and then iterated each over a divide/remainder down to zero. Note that for the fractional part, you must set a reasonable limit for the number of digits - in, say, base 13 you cannot represent 879/1000 (that is from your first example) as any finite series of fractional digits f1/13 + f2/169 + f3/2197 + ... + fn/(13**n), except for a few special cases. (That goes for decimal .879 or .345 as well; they are not represented by those exact values in double format.)
