Depending on what you want to do with the pixels of value 0, you could either replace them with NoData or 1 using Con tool or Reclassify, as suggested by Dan Patterson​

in ArcGIS online??? For arcmap...  why not add 1 to the output, otherwise you have a whole messy reclass to deal with but extending the upper range by 1 shouldn't cause an issue.  otherwise use a Con statement and reclass 0 to some other value, keeping the others the same.
