Raster Calculator Floating Point Data Question

I am trying to use the raster calculator to convert raster climate data from one unit ([mm/year]*100) to another unit (mm/day) so that I can calculated residuals (% difference) between this data (PRISM 1971-2000 precipitation) and future climate projections. However, when I use the calculator it spits out integer data. My question is:

How can I get the raster calculator to output floating point data instead of integer data?

Note: I believe the data is floating point data to begin with. I have also tried using the Float() function.

Thank you

Answered this myself. If anyone stumbles across this you have to take your original raster layer *1.0 (with the decimal) then it will automatically convert to decimals. You can then perform your normal calculation. Another bizarre aspect of ArcGIS 10.
