Well, you should know that `++' and `--' *ONLY* works on variables of type
scalar, where a there is a defined successor or predecessor (You can compare
these operators as the Pascal functions pred() and succ() ), and since a
variable of type float has no defined successor/predecessor `++' and `--'
won't work on it!
