Converting to decimal by default

[Dave Lynam]

I'm importing an excel file and am noticing that it is converting number to fixed decimals by default.  For example, the value 220010 is converted to 220010.0 by Roo.  This is a problem b/c I need to be able to differentiate between 220010 and 220010.0.  Is there a way to disable this default conversion or some other fix?
