For the
accuracy
of
functions other than
shown above,
the error is
±
1
at
the
10th
digit,
as
a
rule.
(In the
scientific notation
system,
the error is
±1
at the
lowest
di
g it of
mantissa display.)
However, the
accuracy will
become
low
around
singular
points and
inflection
points
of
functions.
Therefore,
errors are accumulated in
each
stage of the continuous calculations,
causing
the accuracy to
deteriorate.
(The same applies to other continuous
calcula-
tions made by the
computer
such as
y
and
\YY.)
