Calculation Ranges 24
•
Within the ranges specified, this calculator is accurate to
±
1

increases in continuous calculations due to accumulation of
each calculation error. (This is the same for

Additionally, a calculation error will accumulate and become larger

Calculation Ranges 24
•
Within the ranges specified, 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,
etc., where continuous calculations are performed internally.)
Additionally, a calculation error will accumulate and become larger
in the vicinity of inflection points and singular points of functions

Within the ranges specified, this calculator is accurate to

Additionally, a calculation error will accumulate and become larger

Calculation Ranges 24
•
Within the ranges specified, this calculator is accurate to
±
1

increases in continuous calculations due to accumulation of
each calculation error. (This is the same for

etc., where continuous calculations are performed internally.)
Additionally, a calculation error will accumulate and become larger

Calculation Ranges 24
•
Within the ranges specified, 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,
etc., where continuous calculations are performed internally.)
Additionally, a calculation error will accumulate and become larger
in the vicinity of inflection points and singular points of functions
.
