There is a quick-n-dirty solution. Set $MinPrecision = 100 And then enter numbers something like x = 1.01`2; You will be getting warnings as Precision::precsm: Requested precision 2.` is smaller than $MinPrecision. Using $MinPrecision instead. but in this way you if you want to change precision you just change $MinPrecision value. In[21]:= x ...

The last column seems in error. Here's a workaround for the sample problem, although it does not fix NDSolve`FiniteDifferenceDerivative: dx2 = dx1; dx2[[All, -1]] = -Reverse@dx1[[All, 1]] (* {-0.50000000000000000000, 0.25989153247414500869, -0.29289321881345247560, 0.36161567304292239214, -0.50000000000000000000, 0.80995720221088751026, ...
