Assume $\ulp(v) = 2^k \ulp(r)$, with $k \geq 0$; then the error on $r$ is bounded by $\frac{1}{2} (2^k+1) \ulp(r)$. We can thus write $r = (e^{2x}-1) (1+\theta_3)^{2^k+1}$, -and then $s = \tanh(x) (1+\theta_4)^{2^k+4}$. +and then $s = \tanh(x) \cdot (1+\theta_4)^{2^k+4}$. \begin{lemma} For $|x| \leq 1/2$, and $|y| \leq |x|^{-1/2}$, we have: |
