- 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.
