Exp function to get antilog

I am trying to take some result values and log transform them with the field calculator, then krig them to a surface - I found this in the help regarding the log function:


"field calculator uses the natural Log not Log10(x)


Log ( [Area] ) / Log ( 10 )"


I did that and it seemed to work, but how do I calculate the antilog or exp back correctly of the surface, I can't seem to get back to values that correlate to my original data (which ranges from 0.00001 to 0.003047) - I run:




in the raster calculator and end up with values of 0.00252001 to 0.0755711...I'm wondering if there's a reverse of the above trick to get the antilog of my surface somehow (i.e. get back from Log transformed data to original)? My mathematics are not strong...thanks for any help!
