@PaulCommentary Programatically one can find many ways and I'm not going to list them all, I recommend doing it manually: press ctrl+f write the bactick in the window find and in the window replace don't write anything then continue pressing replace and find next until you complete your task.

@Artes Oops. I had typed $MachinePrecision. That dollar signs, apparently get munged. I might have caught it in a response. But not a comment, as they don't show what the result will look like.

@DanielLichtblau I have rather different observation : MachinePrecision === N[MachinePrecision] yields False while MachinePrecision == N[MachinePrecision] yields True. The same with E and Pi.

No need to numerically evaluate MachinePrecision. $MachinePrecision serves that purpose. In[14]:= $MachinePrecision === N[MachinePrecision] Out[14]= True

@Joseph MachinePrecision is a symbolic constant like Pi and E. You can see its value using N[MachinePresicion] as well. This is what Artes did with Precision[1/3 // N] // N . Rounding gives the approximate (integer) number of digits of precision it corresponds to.
