Is there any way to handle scientific precision in base 10 in a simple
way, using sage ?
Alternatively, are there any libraries that will do something like
that ?
Using \sage{RIF10(RR10(#1))} in a LaTeX document (#1 is the argument)
leaves numbers like 6.0421?e-27. Use of question marks like that is
unheard of in experimental sciences (at least in journal articles). In
any case, a simpler, more direct approach is preferable (all these
field definitions leave open the chance for a mistake that could lead
to an unacceptable loss of accuracy).
For instance, something like sprintf('%e12.3',#1) would be lovely.
The sense I have gotten so far is that numerical related work is an
afterthought in Sage and that it is really a professional
mathematician's workbench that could be coaxed or tweaked into being
useful for scientists who use math / numerics as a tool, and not an
end in itself.
I have nothing against mathematicians (btw).
