New LONGREAL modules

[Mike Griebling <grieblm@trt.allied.com>]

The following modules are now available from the cognac site and can be
considered to be in beta test:

	LowLong.Mod
	LongConv.Mod
	LongStr.Mod
	LongMath.Mod
	OakMathL.Mod

Please note: Both OakMath & OakMathL call routines in RealMath/LongMath and
not vice-versa.

As always, if you have any problems or bugs with these modules please let
me know.

Exceptions are still not implemented as I'm waiting for someone to define
our global exceptions.

I have one question: when converting LONGREAL strings should the number
use a "E" or "D" exponent?  Currently, the LongStr module expects "D"
exponents while the RealStr expects "E"s.  This is contrary to the ISO
standard but more in keeping with Oberon-2 conventions.  All numbers are
converted to strings with the "E" exponent.

Enjoy,
	Michael
