How large, how exact

The calculator works with Numbers up to $\displaystyle 9.999999999 \times 10^{99}$. A Smaller value, below $\displaystyle 10^{-99}$, counts as zero. For Accuracy, an answer is exact to $\displaystyle \pm 1$ in the tenth digit, and the error grows in long chains of calculations. The Functions each have their own range: the calculation examples sheet lists them all.
