fix: improve efficiency and accuracy of value_cast for quantity_point ( #765 )
...
Rewrite the quantity_point overload of sudo_cast to pick the best
intermediate unit/rep for each conversion case:
- Same origin: delegate entirely to the quantity sudo_cast (unchanged).
Also fix a pre-existing bug where the result was incorrectly tagged
with FromQP::point_origin instead of ToQP::point_origin.
- Same unit, different origin: skip unit scaling altogether; compute the
origin offset in the common rep and add it directly.
- Different unit, floating-point rep: pick the larger of the two units
as the intermediate (to minimise the scaling magnitude), then use
point_for() to let the library's common-unit arithmetic handle the
origin shift — this avoids the binary FP precision loss that occurs
when the offset is expressed explicitly in the larger unit.
- Different unit, integer rep: prefer the output unit as intermediate so
no extra scaling is needed after the offset addition. If the origin
offset would overflow the output-unit type, fall back to the input
unit where it is guaranteed to fit.
Also expand the value_cast tests for quantity_point to cover every
branch explicitly, including the new integer overflow-fallback path.
