2013-01-16 05:19:09 +0200 | marked best answer | extracting digits in p-adic expansion But note that here the coefficient of $3^9$, which is zero, yields [] as its list of coefficients. Similarly, for the coefficient of $3^4$, which is $2$, we get [2]. |

2013-01-15 10:20:05 +0200 | asked a question | extracting digits in p-adic expansion Here is a maybe naive question. I am working over an unramified extansion of $\mathbb{Z}_p$ (let say of degree 2), say R.(c) = Zq(7^2) so that every element of R is written as ($a_0$ c + $b_0$) + ($a_1$ *c + $b_1$) *7 + ($a_2$c + $b_2$)*7^2 + $\ldots$ . Is there a command to extract each of the $a_i$ or $b_i$ individually ? |
