Did you read what I wrote? The code you wrote has nothing to do with the expression I gave. How about
DECLARE (I, J) FIXED DECIMAL (15); I = 4; J = 3; PUT ((I/J*J)); -- Shmuel (Seymour J.)

You are still wrong. Recently you have made numerous erroneous claims about PL/I. 4 is an integer in PL/I. 3 is an integer in PL/I. > The arithmetic rules for scaled fixed > point are different from those for integers. Scaled, with a scale factor other than zero and with a fractional part, yes, because they are not then integers. However, with scale factor of zero, they are integers. > In integer arithmetic, > (4/3)*6 is 6 That's not the result you get in PL/I. With the following declarations, you'll get the same result in PL/I, namely, 6: DECLARE (I, J) FIXED DECIMAL (15); I = 4; J = 3; PUT (I/J); will print 6 > ________________________________________ > From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> on > behalf of Robin Vowels <robi...@dodo.com.au> > Sent: Sunday, September 6, 2020 7:06 PM > Subject: Re: Constant Identifiers > > ----- Original Message ----- > From: "Seymour J Metz" <sme...@gmu.edu> > To: <IBM-MAIN@LISTSERV.UA.EDU> > Sent: Monday, September 07, 2020 5:33 AM > > >> PL/I doesn't have integers. > > PL/I has always had integers. > >> The ratiio 4/3 is FIXED BIN, > > No it not.
