<<why are you re-casting variables that are already in the proper cast.
The only time you need to re-cast a variable into float is when the
variable is an integer.>>

This is quite wrong, it would be true in C, but is not just false for Ada.
It is the *essence* of a critical feature of Ada that it is false! In the
example you were commenting on, the float types were different types,
and the casts, called type conversions in ada, were definitely necessary.
