FLX-5004: declared grid parameter is invalid or not representable
Family: numerics (the 5000 band)
A grid parameter does not describe a usable grid: fractionalBits out of range, an interval whose bounds are the wrong way round, or histogram edges that are not strictly increasing grid points. Binning is exact only when every declared edge lands on the grid.
