Fortran

I'm amazed that there is not a Fortran example for this yet. Since the ISO 1990 (1991?) standard (commonly called Fortran 90), Fortran has had some of the richest language-based (not library-dependent) floating point support around. ISO 2003 adds specific optional support for IEEE numbers too IIRC. I'll try to put together an example if I can find the time, but I no longer have access to a current Fortran compiler. --Balrog 09:19, 5 March 2011 (UTC)

REXX

not quite?

something=3; format(something,,,,0) yields '3' (on ooRexx) --Walterpachl 18:27, 27 August 2012 (UTC)

Yes, I adjusted the explanation for the "rule" for the FORMAT bif for the fifth argument being zero.
Note that if <lang rexx>something = 3.0 say format(something,,,,0)</lang>should return

3.0

not

3

I didn't say that, did I? ooRexx returns 3.0 for this!--Walterpachl 20:33, 27 August 2012 (UTC)
No, I wasn't referring to ooRexx, but one of the common REXX interpreter used does, and I didn't want to name it specifically, but I thought it was worth the mention as there'll most likely be some finger pointing about which REXX does what, and what is the one and true answer. When confronted with problems like this, I like to go back to King Soloman, er I mean, VM, and ask, what would CMS REXX do? By the way, Personal REXX, PC/REXX, R4, ROO, and now ooRexx all agree. That leaves the odd man, er, REXX, out. It would be nice if a CMS and TSO REXX whould chime in. -- Gerard Schildberger 20:41, 27 August 2012 (UTC)
So we found another difference between classic (as you call it) and ooRexx. The following is specified in ooRexx' manual:
If expt is 0, exponential notation is always used unless the exponent would
be 0.

what does Regina say for format(3,,,,0) ? --Walterpachl 06:04, 28 August 2012 (UTC)
