MicroscopicErrorPlot


plots the error incurred by using machine arithmetic to evaluate the expression f in a small neighborhood of a.

plots the error from ulps to ulps.
  • The scale on the vertical axis represents the error in ulps.
  • The following option can be given:
JoinedTruewhether to join points
  • With the setting Joined->Real, the line joining the plot points represents the mapping from the set of real numbers to the error in the machine-number output.
