Re: [Gm2] REAL precision

[Andreas Fischlin]

Dear Scott,

I fully agree that REAL = "IEEE single precision real" and LONGREAL = "IEEE double precision real" is the approach most M2 implementations follow. Thus I would therefore even argue that this should actually be the default and REAL = double precision should be the option you have to request. But, agreed, this argument depends on what one wants to accomplish with gm2: Legacy code or modern, state-of-the-art implementation of a Modula-2. The former calls for default is REAL single/LONGREAL double, the latter would rather opt for leaving the defaults as they are now (if I all understood correctly).

Regards,
Andreas

Hi Gaius,

By default GM2 translates the REAL type as a double precision number.
Is there a way I can build the compiler with REAL=float, and
LONGREAL=double?  Or perhaps persuade you to make REAL=float the
default bahavior? That's been the convention for every other M2
compiler I've used...

Anyone else have a preference for REAL=float or REAL=double?

Also for Gaius: I sent a message on June 17 reporting a new problem
and inquiring about the status of an earlier bug report.  Did you
receive that message?

Thanks,
Scott
