           Summary: DecimalFloat spec doesn't match dmd behavior
           Product: D
           Version: 0.149
          Platform: Macintosh
        OS/Version: Mac OS X
            Status: NEW
          Severity: normal
          Priority: P2
         Component: www.digitalmars.com
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: braddr@puremagic.com


The documentation currently describes DecimalFloat as:

DecimalFloat:
        DecimalDigits .
        DecimalDigits . DecimalDigits
        DecimalDigits . DecimalDigits DecimalExponent
        . DecimalDigits
        . DecimalDigits DecimalExponent
        DecimalDigits DecimalExponent

I believe this is incorrect.  It should be, by my reasoning:

DecimalFloat:
        DecimalDigits .
        DecimalDigits . DecimalDigits
        DecimalDigits . DecimalDigits DecimalExponent
        . Decimal
        . Decimal DecimalExponent
        DecimalDigits DecimalExponent

The reason I believe this to be is simple.  Try the following code:

writefln(._1);

According to the previous definition of DecimalFloat (as far as I read it), that should be equivalent to:

writefln(.1);

However, it instead generates an error with DMD.  I think this makes the most sense, and serves to clarify that this:

writefln(._);

Is also not a FloatLiteral (which I think is pretty clear.)
