Calculation Ranges
• Within the ranges specified, this calculator is accurate to
±1 of the least significant 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
¿
,
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 inflection points and
singular points of functions.
• Calculation ranges
±10
-99
~ ±9.999999999×10
99
and 0.
If the absolute value of an entry or a final or intermediate result
of a calculation is less than 10
–99
, the value is considered to be
0 in calculations and in the display.
