comment Multidimensional arbitrary precision spline interpolation on the grid
@Shutao, I wouldn't be that confident. :) Sometimes, there are situations where MachinePrecision can be insufficient (e.g. finding intersections); it's always useful to have a safeguard against loss of significant digits.

comment Multidimensional arbitrary precision spline interpolation on the grid
That's correct. The only reason for showing the plot is to visually demonstrate that the explicitly-constructed B-spline is equivalent to the output of Interpolation[]. If you want to force the use of higher precision, the plotting functions all accept a WorkingPrecision setting. The explicitly constructed B-spline will keep up; the InterpolatingFunction[] will still be stuck at MachinePrecision.

Added bugs provisionally; we now need someone with version 9.x to test.

Looks like a bug; what version are you on? It's unevaluated in 10.2.
