I want to set null all raster values that fall below the 75th percentile value. E.g. If you classify the raster by quantile method into 4 classes I want to be left with the top 25% percentile. For the raster shown below, 3.154941635 would be used in the set null expression.
I have attempted the following in the Calculate Value tool and a value of 0 is being returned. (source:https://community.esri.com/thread/162022)
