# Class FixedPoint, version 0.0.4.

FixedPoint objects support decimal arithmetic with a fixed number of
digits (called the object's precision) after the decimal point. The
number of digits before the decimal point is variable & unbounded.
The precision is user-settable on a per-object basis when a FixedPoint
is constructed, and may vary across FixedPoint objects. The precision
may also be changed after construction via FixedPoint.set_precision(p).
Note that if the precision of a FixedPoint is reduced via set_precision,
information may be lost to rounding.
FixedPoint - + % and divmod are always exact.
FixedPoint * and / may lose information to rounding, in which case the
result is the infinitely precise answer rounded to the result's precision.
