I want to increase the precision globally to
50 at least, but
$MinPrecision does not work.
$MinPrecision = 50; x = Sin[2.] (* -> 0.909297 *) Precision[x] (* -> MachinePrecision *)
How to set the working precision globally, i.e., make all the calculations in the notebook use the new precision?
2.and you will get the effect you are after. $\endgroup$
