algebraic
The exact real root of a square-free polynomial (degree 3 or more) that lies in the open rational interval (lo, hi) -- checked to be the only root there.

Algebraic Numbers
sign
Of an algebraic number: negative, zero or positive. Of an ordinary number, the signum function: -1, 0 or 1.
a(algebraic) --
refine
The same root with its isolating interval halved.
a(algebraic) --
sameRoot
True if two algebraic numbers are the same real number.
a(algebraic) --b(algebraic) --
compare
less, equal or greater: a against another algebraic number or a rational (refine first if the intervals overlap).
a(algebraic) --b(algebraic | number) --
affine
scale * a + offset, exact.
a(algebraic) --scale(number) --offset(number) --
square
a^2, exact.
