mCeiling
Option<F32> = 0 Upper bound of the sum. When it is not set, the sum has no upper bound.
A calculation part that returns the sum of
mSubparts, clamped to mFloor and mCeiling. Null entries are skipped. The client
tests the ceiling first: if mCeiling is set and the sum is above it, the part returns
mCeiling. Otherwise, if mFloor is set and the sum is below it, the part returns
mFloor.
Option<F32> = 0 Upper bound of the sum. When it is not set, the sum has no upper bound.
Option<F32> = 0 Lower bound of the sum. When it is not set, the sum has no lower bound.
The parts to add before the clamp.
