c.norm() for complex c
---------------------------+------------------------------------------------
Reporter: mvngu | Owner: tba
Type: enhancement | Status: new
Priority: major | Milestone: sage-4.1.1
Component: documentation | Keywords: absolute value, complex norm
Reviewer: Alex Ghitza | Author: Minh Van Nguyen
Merged: |

Comment(by cremona):
I agree. Blame the number theorists! In number theory there are lots of
norms with different norm-alizations (joke) which causes a lot of
confusion. In the implementation of local and global heights for number
field elements the same issue arose (see #6046, now merged): for complex
embeddings there is an issue of whether or not to multiply by 2 (which is
the logarithmic equivalent of the current discussion) and I allowed both,
with a boolean "weighted" parameter to switch between them.
