Calculation ranges of functions
• Within the ranges specifi ed, this calculator is accurate to within ±1
of the least signifi cant digit of the mantissa. However, a calculation
error increases in continuous calculations due to accumulation of
each calculation error. (This is the same for fi nancial calculations,
scientifi c calculations [ y
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.
In fi nancial calculations, a calculation error increases if the
interest is low or the number of payments is high. Press s
if you'd like to cancel the calculation while the "calculating!"
