## Avoiding infinity in pow and /

Taking 0 to the power of any negative exponent equals infinity. In Max, this yields the unique *float* value *inf*. In cases where you want to avoid getting *inf*, and would prefer to get *0*, you can simply make a special case for a *0* input, and pass it on directly, avoiding the **pow** object. On the left is an example of how to use **routepass **to force Max to output 0 when it would otherwise calculate infinity, such as when using a **pow -1 **object.
