Puzzle

I have been fighting with a possible problem which is exemplified in the
following program:

---------------------------------------------------------------------
say "Double(2.9)="Double(2.9)
say "Double(double 2.9)="Double(double 2.9)
---------------------------------------------------------------------
The results from "nrc -run" are:

Double(2.9)=2.9
Double(double 2.9)=2.9

The results from "nrc -exec" are:

Double(2.9)=2.9000000953674316
Double(double 2.9)=2.9

I have checked that these results are the same for all versions of
NetRexx back to 2.05.

Is this a bug or is it supposed to be that way and if so is it
documented somewhere? Is it a NetRexx issue or is it a Java issue?

Re: Puzzle

Hence, then, Walter Pachl & Kermit Kiser,
we shall then *go back/up/back up)

*to the so well sesigned Syntax & Semantics* of PL/I, those Days, *or
what* ???

Walter, you *PLI* GURU, please do *write a reliable answer* (when your
time does allow, only, of course!)

/* NetRexx */
options replace format comments java crossref symbols nobinary
say "Double(2.9)="Double(2.9)
say "Double(double 2.9)="Double(double 2.9)

gives me

Double(2.9)=2.9
Double(double 2.9)=2.9

Funny:
NetRexx portable processor, version NetRexx 3.01RC3, build 21-20120806-0031
Copyright (c) RexxLA, 2011,2012. All rights reserved.
Parts Copyright (c) IBM Corporation, 1995,2008.
Program dot.nrx
NetRexx 3.01RC3
===== Exec: dot =====
Double(2.9)=2.9000000953674316
Double(double 2.9)=2.9
Processing of 'dot.nrx' complete

That's the other way round!

Tom: This has nothing to do with generic functions in PL/I
PL/I Builtin functions are 'generic' by nature

An aside: Compilers are sometimes better than interpreters (think of Rexx(TSO)
and sometimes help to improve the latter :-)

I don't notice any difference, but then I've been seeing double (precision) lately anyway.

Sorry!

Walter:

Who is *now* the Culprit ?

Definition of *Numbers* (any dialect) in Rexx&/Netrexx, *or what* ??

Tom Maynard:

*Attention*, *please*, with Walter Pachl:

1.) He is from Vienna, Austria!
2.) He *has been* QA Test Manager at the IBM_Laboratories, here, in
Vienna, under
the already dead *Professor Zemanek*, IBM, who did *invent* the
*MAILÜFTERL*,
the first *Transistor based: * --- Google the MAILÜFTERL, and Zemanek!
3.) As I am already *from Vienna*, I did have the advantage to *have*
*Prof. Zemanek*
as a teaching *professor* when I did stuy *Technical Mathematics*, here,
in Vienna.
4.) He is *known* ( I do mean *Walter Pachl*, here, to detect *any and
all faults*
a Software might have ...

Thus, please all:

Consider, when Walter *does report a Problem/Bug* then it is:

*A Problem/Bug* !!!!!!!!

End of my (personal) advise, hopefully allowed here!

Thomas.

May I correct two things:

Professor Zemanek is NOT dead at all.

And he wasn't Manager oft he Lab when I tested the Rexx Compiler, so this was not 'under'.

And please, Tom, stop praising my virtues!

Walther, please *do call me* Thomas ;-)

1.) Great to hear that Prof. Zemanek is still alive!
2.) Maybe I did mix something up: *BUT*

For Sure, Walter Pachl has been the *acting* IBM Rexx Compiler QA Test
Manager, here, in Vienna,
at the *no longer existing* IBM Lab's, in Vienna, Austria!

3.) For all of you: Walter did help me a lot, some years ago, to
*implement* the PL/I
version of www.db-123.com.

4.) However, he *does* personally, frefer writing *mails* instead of
personal meetings....

So what ?

Walter, stay, as you are, please!

You are, and always have been, *excellent*, whatever you did!

Do forget your 72 years of age, your *brain* is still: *excellent*

Mine is: Sometimes *cumbersome*, for others ...

(and me, as well, of course)...

Thanks a *lot* Chip, for talking directly with me, again, and answering:

Frank Question, Mr. Ex-RexxLA, president, and Reene, and all, as well:

*Do you think* (personally, Chip, you, and Mark Hessling, and Rick, and
Mike, and Rene, as well):

Do you *think* that we *can and should try* to make out of the existing
*Rexx Family of Languages*
a *new Language* (I did call it Rey, all of you do know, for years)

As *REX* has been, which did become *Rexx*, etc, etc etc

*REY* might be the (logical) *antecestor*, maybe ?
