firstly great apologies for the delay in responding to many emails..
my desktop motherboard failed which disrupted email for half of the
week.  I hope to catch up on many known outstanding emails on Monday.
Then later on in the week had to be

In the meantime - here are the latest cvs changes.  Main changes are
to fixing REAL/LONGREAL bugs in the compiler and also some of the
Logitech compatible LONGREAL -> string conversion routines.  Also
included are a number of runtime regression tests to ensure that the
recent critical math related bugs reported are detected.

I've modified the
gm2/gm2-libs-pim/RealConversions.mod:LongRealToString description - to
make it easier to use and understand what results are expected.  The
original definition module was not clear (to me).  If anyone can
explain (maybe with examples what values the original would give
I'll happily re-implement it :-)

Finally I get a clean sweep of regression tests on LP64 Athlon Debian stable.

# of expected passes            6774


# of expected passes            6750

on Ubuntu x86_64 (Intel(R) Core(TM)2 Duo CPU)

(hmm looks as if four of the regression test files have not yet been
checked in)

        * testsuite/gm2/pimlib/logitech/run/pass
          added runtime tests to check the values of REAL and
          LONGREALs once converted.
        * gm2/gm2-libs/FormatStrings.mod:  tidied up comments.
        * gm2/gm2-libs/MathLib0.def:  entierl (new function).
        * gm2/gm2-libs/MathLib0.mod:  entierl implement
          (new function).
        * gm2/gm2-libs/StringConvert.def:  added example of
          use to the comments.
        * gm2/gm2-libs/StringConvert.mod:  DetermineSafeTruncation
          tidied up comments and added examples, fixed bugs.
        * gm2/gm2-libs-pim/RealConversions.def:  tided up comments
          and added examples.  LongRealToString and ReadToString
          now take an INTEGER width which matches the Logitech
        * gm2/gm2-libs-pim/RealConversions.mod:  RealToString and
          LongRealToString modified width parameter to take an
          Reimplemented much of LongRealToString and altered its
          definition to make it simpler to use.

2008-12-05       Gaius Mulley <address@hidden>

        * fixed bug reported by Steve Giess <address@hidden>
          which showed const+realvar was not converted to the
          required REAL/LONGREAL/SHORTREAL type when passed
          to a procedure.
        * gm2/gm2-compiler/M2GenGCC.mod:  ensure that actual
          parameter are converted to formal parameter types if
          they are a member of the real type family.
        * testsuite/gm2/pim/run/pass/mathconst.mod:  new file.
        * testsuite/gm2/pim/run/pass/math.mod:  new file.
        * testsuite/gm2/pim/run/pass/math2.mod:  new file.
        * gm2/gm2-compiler/M2Base.mod:  fixed MixTypes to
          handle expressions of RType and (REAL|SHORTREAL|LONGREAL).
