Re: FP number syntax

A forth that interprets e.g. 3.14 as a floating point number
is as non-standard as a Forth that interprets 3.14 is a double.

Forth-94 and Forth-2012 do not standardize recognizing 3.14, so
standard systems are allowed to deal with "3.14" as they deem useful.
The possible options include recognizing "3.14" as a double-cell
integer, as a FP number, or not recognizing "3.14" and producing an
error message.

However, I think that recognizing "314." as a double-cell integer (as
required by these standards), but recognizing "3.14" as an FP number
is even more confusing and error prone than recognizing both as a
double-cell integer.

How would a proposal like this fare:
"
   A double number is only recognized as it ends *and starts*
   with a period.

Existing practice?  What's wrong with "#314."?

   Recognizing a double if it ends only in a period becomes
   obsolescent.
"

That part may have an easier time.
