New description:
I am working on implementing significance arithmetic in Sage (i.e.,
maintaining significant digits under arithmetic operations). This can be
accomplished through a special structure which, upon instantiation,
determines the amount of sig. figs and coerces into a !RealField.
For example,
{{{
sage: SF('787') * SF('3.0')
2400.
}}}

Comment(by leif):
Shouldn't the result display as something like `2.4 * 10^3` (`2.4e3`) or
`24 * 10^2` (`24e2`)?
