The format is set by default to display integer values.
Set the FORMAT keyword to whatever you prefer. Something
like this should work:
Colorbar, ...., FORMAT='(F0.2)'

I typically set up some kind of map projection and then
warp the image into that. Labeling the axes correctly
then becomes a bit trickier. It would help if I knew
more about your image and what you are trying to do,
exactly.
