So, you are saying, don't make all current floats doubles,
but make a double out of anything I define by hand: a=24.5.

But, what happens when I multiply my 10000x10000 floating
point array by my variable: array = array * a.

That will *surely* double the memory, or do we need new
rules for promoting values?

Cheers,

David
