- appears to hit single precision overflow with clang-15 in
face::center(), cellModel::center() and blockMesh createPoints().
The blockMesh might be particularly sensitive, since the points are
frequently defined in millimeters (scaled later), which results
in large intermediate summations.
Similar to primitiveMesh checks, use double precision for these
calculations.
ENH: support vector += and -= from compatible types
- eg, doubleVector += floatVector is now supported.
This streamlines some coding for mixed precision.
- To avoid lots of boilerplate, do not yet attempt to support general
operations such as `operator+(doubleVector, floatVector)`
until they become necessary.
- similar to what std::copy_n and std::fill_n would do, except with
templated loops. This allows compile-time transcribing with loop
unrolling. For example,
vector vec1 = ..., vec2 = ...;
FixedList<scalar, 6> values;
VectorSpaceOps<3>::copy_n(vec1.begin(), values.begin());
VectorSpaceOps<3>::copy_n(vec2.begin(), values.begin(3))
// do something with all of these values
STYLE: make start index of VectorSpaceOps optional
ENH: add clamped begin(int) versions to FixedList as per UList
