Trouble with Reclassify tool

Question

I am trying to reclassify a slope layer I have into a scheme where is it 0-1,1-2, 2-3, etc etc... but when I enter New Values in the reclassify table as 0-1, 1-2, etc. It gives me an error message saying New Value can only integer or NoData when I try to save the table. On the tool help menu, it states that New Values can be either integer  or ranges separating the numbers with a hyphen. When I try to run the reclassify tool with these ranges in the New Data part of the table it fails to reclassify. Anyone know how I can reclassify my slope layer? It is still a floating point raster I think if that helps..

I'm trying to create a reclassifed raster DEM to just 2 vaules and the reclassify tool keeps defaulting to 9 values. Under the classify button, manual, or any type for that matter, does not allow you to change the number of classes.

Also having issues with error message associated with precision.

Any suggestions are welcomed.

Thanks,

Dave

UPDATE: found the issue had to do with some spurious values in the raster. Checking the box "change missing values to no data" gave me the 2 value result I was looking for.

Thanks for responding. I got it to let me reclassify only once before it stopped letting me do anything again. I am just going to use 9.2 tomorrow at my intership.

If you had run the tool, regardless of whether it failed or succeeded, you should change the output name to something different when running it again.

Even clearing the results doesn't always help.

example, if your first output was called Slope.tif, then change the next output to Slope1.tif

but good luck with your research.
