Curiuously enough, I am working on adding real types to Mneson, and 
currently I have only decimal fixed point types:

"Real values are represented by decimal fixed point types Giganano, 
Megapico, Teramicro. The name of each type indicates its range and 
precision, e.g. Giganano values range from -1G to 1G with a precision of 1n.

Not published yet. Comments welcome. The types are constrained by Ada 
(or GNAT) limit of 18 digits, and the available size is 64 bits which is 
consistent with that. This experiment made me realise that 64 bits is 
tight for any sort of universal real type implemented as fixed point. So 
I created three types, not one. And I'll leave it like this until 
evidence that float or binary is needed. Comments welcome. Mneson is a 
database system.
