I'm learning about P-adics, and would like to play around a bit with 10-adic numbers, to follow along with some tutorials.
Unfortunately so far all ways I've tried to create 10-adic numbers in Sage resulted in the error "p must be prime".
I understand non-prime-adics have their issues, but can I still make it work somehow?
PARI/GP supports $p$-adic numbers with non-prime $p$:
This can be used inside Sage:
sage: a = gp('1 + O(10^3)')
sage: a
1 + O(10^3)
sage: a + 100
1 + 10^2 + O(10^3)
You can define infinitely long decimal numbers, but you can not divide such numbers in any case. This numbers form a ring, but not a field. Therefore the error message.
