Why don't we switch to C like floating pointed arithmetic instead of automatic expansion to reals?

Java originally came out with an edict that floats will all be done in float 
precision, and double in double.

Sun had evidently never used an x87 before, because it soon became obvious that 
it was unworkable on the x87, and the spec was changed to allow intermediate 
values out to 80 bits.
