Abstract
We consider arithmetic expressions over operators $+$, $-$, $*$, $/$, and $\sqrt{\ }$, with integer operands. For an expression $E$, a separation bound $sep(E)$ is a positive real number with the property that $E\neq 0$ implies $|E| \geq sep(E)$. We propose a new separation bound that is easy to compute an d stronger than previous bounds.
