Determine the range of values in one raster associated with certain values in another raster

[ThomasTaggart]

I have two rasters, one with thematic data, and the other with continuous data (floats). I am trying to calculate/determine the the range of float values associated with the different classes in my thematic raster. For instance, in my thematic raster, I have a class A. If there are 5 cells in my continuous raster data that overlay thematic cells of class A, and these 5 cell have values of 1.2, 3.7, -4.5, 6.23, -0.8, I would like the end result of my calculation to show:

Class A:  Range [-4.5 to 6.23] 
Class B:   .....and so on. 

Does anyone know of a way to do this? I've been trying to determine if the raster overlay tools in ArcMap can provide this, but I haven't come across a solution yet. I'm hoping to avoid a very complicated equation in the raster calculator.

Another way to produce the analysis I am looking for would be to generate a histogram for each thematic class in one raster based on the associated (overlaid) values in another. Is this possible?

Zonal statistics as table will do the job with the caveat that you may have to do a

Region group ​first since a class can consist of many discrete parts separated like a multipart vector feature and if you want the statistics for all areas with a different spatial separation but the same class, they need to be identified separately​​
