[Cin] Plugins in integer or in float

From the source code we can tell if a plugin works in 32 bit float or 8/10 bit integer? I don't know, maybe by searching for the string "float" in the code or something like that? Or the normalized range (0-1.0) instead of the range (0-255), etc. It would be important to put this information in the manual because, for example, I know that Histogram works with integers and this can lead to clipping (with loss of information) in highlights or deep blacks. In contrast, Blue Banana works in floats.
