Generally, no. It's also hard to do in a general Array, since each  
Float is a full object, any arithmetic on it does unboxing and boxing  
of a newly allocated Float object. To speed this up considerably you  
would have to create primitive array that do not hold objects but.

There is the class FloatArray which works on a primitive array of 32- 
bit floats, but only very basic operations are supported by the
