Calculation Ranges
• Within the ranges specifi ed, this calculator is
accurate to
±1 of the 10th digit of the mantissa.
However, a calculation error increases in
continuous calculations due to accumulation of
each calculation error. (This is the same for
y
x
,
x
r, n!, e
x
, ln, Matrix/List calculations, etc., where
continuous calculations are performed internally.)
Additionally, a calculation error will accumulate
and become larger in the vicinity of infl ection
points and singular points of functions.
• Calculation ranges
±10
−
99
to ±9.999999999 × 10
99
and 0.
If the absolute value of an entry or a fi nal or
intermediate result of a calculation is less than 10
−
99
,
the value is considered to be 0 in calculations and in
the display.
Display of results using r
Calculation results may be displayed using r when all
of the following conditions are met:
• When intermediate and fi nal calculation results are
displayed in the following form:
±
a
P
b
⎯
e
±
c
P
d
⎯
f
• When each coeffi cient falls into the following ranges:
1
≤ a < 100; 1 < b < 1,000; 0 ≤ c < 100;
1
≤ d < 1,000; 1 ≤ e < 100; 1 ≤ f < 100
• When the number of terms in the intermediate and
fi nal calculation results is one or two.
Note: The result of two fractional terms that include r
will be reduced to a common denominator.
