| Jan 26, 2016 at 23:13 | comment | added | Lubin | Often, when the radix is not (a power of) a prime, they’re called “$g$-adic numbers”, and OP may have success in searching for that term. Additionally, I might point out that $\sum_0^\infty 9\cdot10^n$ is convergent to $-1$ not only $10$-adically, but also $2$-adically and $5$-adically. | |
| Jan 26, 2016 at 15:47 | comment | added | Paul Sinclair | One thing to note: they are called the "$k$-adics" for a reason - unless $k_1$ is a power of $k_2$ or vice versa, the $k_1$-adics and the $k_2$-adics are different rings. So the 10-adics are not the same as the 2-adics. For example, the 10-adics has 0-divisors, while the 2-adics form a field. | |

| Jan 24, 2016 at 12:55 | comment | added | wythagoras | Are you really sure that you don't have everything screwed up in your table? In particular, I have seen reals with infinitely many digits after the point, like pi, but a real number can't have infinitely many digits before the point. (I know nothing about p-adic numbers, so I won't edit) | |
