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 yx, x , n!, ex, 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. Calculation ranges 1099 ~ 9.9999999991099 and 0. If the absolute value of an entry or a final or intermediate result of a calculation is less than 1099, the value is considered to be 0 in calculations and in the display.
