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

PL/I doesn't have integers.
PL/I has always had integers.
The ratiio 4/3 is FIXED BIN,
No it not. It is FIXED DECIMAL -- as I said a few days ago.
And it hasn't changed since.
with some number of bits after the binary point.
DECIMAL digits after the decimal point, because the result
is FIXED DECIMAL, not binary.
