I'm not sure that's relevant: all machines can mimic single float  
(i.e. the double hardware can do single rounding after every operation).

I'd be more interested in hearing how big a user base double-precision  
floats really have. Are many scientific data sets encoded using doubles?

For the record, I'd wouldn't mind requiring double-precision floats  
but only 32-bit integers. Minimal implementations of such a spec could  
use a single homogeneous representation for numbers in that case.
