The DOMAIN/CommonLISP Reference Manual p.12-6 says:
"Common Lisp designates four floating-point number formats:
short-float, single-float, double-float, and long-float. ...
DOMAIN/CommonLISP represents all four types of floating-point
numbers in the single-float format." I had previously
discovered this for myself.
I expect some Apollo machines have double-floats. True?
So, I guess this just means that Lucid has decided not to give
its users access to Apollo double-floats at this time?
Can anyone clarify this?
Lucid only wants to support one floating point format. I am told that a future apollo
version will support double floats, at which time it will cease to support single
floats. sigh...
