 Oct 20 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. Oct 20 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.
