MicroscopicErrorPlot
MicroscopicErrorPlot[
f
, {
x
,
a
}]
plots the error incurred by using machine arithmetic to evaluate the expression
f
in a small neighborhood of
a
.
MicroscopicErrorPlot[
f
, {
x
,
a
,
n
}]
plots the error from
a
-
n
ulps to
a
+
n
ulps.
MORE INFORMATION
To use
MicroscopicErrorPlot
, you first need to load the
Computer Arithmetic Package
using
Needs
["ComputerArithmetic`"]
.
The scale on the vertical axis represents the error in ulps.
The following option can be given:
Joined
True
whether to join points
Valid settings for
Joined
are
True
,
False
and
Real
.
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.
