Calculation Ranges

s 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

r, n!, e

, ln, Matrix/

Vector calculations,

3, 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
