What's the opposite of the Power Tool?

I feel dumb asking this but I have been provided a raster where "...raw attribute values have been multiplied by
a power of 10 to retain attribute precision." It stands to reason that I need to do the opposite of this to get back to the original raster values.

From the various tools found within the Spatial Analyst Toolboxes, the Power Tool creates the raster that I originally received but I'm at a loss to find the appropriate tool to "undo" what the Power tool did. The help information doesn't mention this so which tool should I use to get the original (valid) values?

Thanks!

Steve

I think what they mean is divide

1.414 *1000 = 1414 your integer retaining 3 decimal places,

1414 / 1000 = 1.414 your decimal

10^3 or 10^2 or 10^1 or whatever was needed to produce the integer, assuming no rounding


... sort of retired...

Thanks, Dan. This did occur to me and so I tried this. When I compared the output to a previous dataset from a couple years back, the converted data seemed wildly inconsistent so that led me to doubt this option. I need to email the contact back anyways so I will ask them about the proper way to revert it back to normal values.
