    This is the best that I've come up with:
         #!/bin/csh
         # This csh script computes x = $1 + $2,
         # where $1 and $2 are floating-point numbers.
         bc << END > temp
         scale = 5
         $1 + $2
         END
         set x = `cat temp`
    
    Can anybody think of a better way?

How about:

    set x = `echo "scale=5; $1 + $2" | bc`

Same effect, less space.
