integer or float?

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

    Accidentally left option forcefloat active
      and a function of mine stopped working.  It boils down to this:
      
      4 /aWorking/Zsh/Source/Wk 4 % cat test
      #!/usr/bin/zsh
      
      integer MAX_INDEX=2
      local idx=        
      for ((idx=$MAX_INDEX; idx>0; idx--)); do
          echo $idx            
      done
      
      4 /aWorking/Zsh/Source/Wk 4 % unsetopt forcefloat; .test
      2
      1
      
      4 /aWorking/Zsh/Source/Wk 4 % setopt forcefloat; . test
      2.
      1.
      
      ... anyway I've figured out that 'integer idx' cures the problem,
      so it seems that forcefloat affects a scalar but not an integer
      which seems backwards.  Also, '1.' is mathematically distasteful
      is it not?  The trailing dot is rude, one might expect '1.0' or
      just leave the dot off when there is no actual float value. 
      Thoughts?
