How can i specify in the otherwise condition of the following equation

\begin{cases}\ U & \text{if $A_{U_{Max}} = A_{U_{Min}} =$ Null},\\ \ \frac{A_{U_{Max}} - A_{U_{Min}}}{U\sqrt{2}} & \text{otherwise} \end{cases}

that if denominator is 0 then make it equal to 1 ?

    How about $U\sqrt{2}+\delta_{U\sqrt{2},0}$ (Kronecker's delta)?2012-04-17

    Or $U\sqrt2+[U\sqrt2=0]$, with an [Iverson bracket](http://en.wikipedia.org/wiki/Iverson_bracket).2012-04-17
