The output of 3dcalc will always have a single datum type. You can force the output to be floats, for example, with the command line option "-datum float". If you want to produce 1 sub-brick of one type and the 2nd of another, then you'll have to do what you suggested - process them separately, then glue them back together. However, except for disk space, there is no reason why you can't use floats for both sub-bricks -- that would be my recommendation under the circumstance that you describe.
