Sage-Devel,
I've been asked to write a review of Sage for SIAM Review, the main
journal for the Society for Industrial and Applied Mathematics. I'd
like to include some concrete examples of some fast and powerful
commands in Sage that would interest applied mathematicians. For
example, Sage
Hi Fergus,
thank you for your comments!
So, do you consider working on a Quantity porting worthwhile? It seems
that you got some good experience by working on it, so you can
probably give some better advice about the structure of that package.
Moreover, I'm wondering how much work would it

What the code does is to assign PP to a suitable projective space. I
imagine that the intention was for the user to provide the ambient

Awesome! Looks like your patch is a little more comprehensive than
what I was planning, I might pick and choose a bit :-)

Regarding the output of such expression you wrote, I agree that it

I am working my way through the Sage 3.4 Tutorial from my local copy of

In fact my idea is a bit different, and I'll explain in a minute:
provided that the system is SI, you should get the result as a
multiplier (bigger than one) of the closest classic unit
representation
ex: meters - nm - um - mm - m - km - ecc ecc
ex:
x1 = 10cm
x2 = 1m
x1 + x2 = 1.1m
y1 = 1V
