Re: truncating a decimal value in /Free

Thanks, Joe.

I had previously considered something similar to Chuck's suggestion but I ended up doing it this way, with fixed-form code in the truncate() subprocedure...

As for using Eval, I suppose I'm an idiot!

A couple of options.

One, do they REALLY want truncation? If not, you might consider using a
max value. Define a field C_MAX as LIKE(FieldA) inz(*HIVAL). Then if
FieldB > C_MAX then FieldA = C_MAX else FieldA = FieldB.

But if you don't like THAT [which I actually don't - it's the one reason
I would really like a ternary operator in RPG like in Java: FieldA =
(FieldB>C_MAX ? C_MAX : FieldB)], then how about this:

FieldA = truncate(FieldB);

Write your truncate procedure and you can even use fixed format code in
it - hide it at the bottom and nobody will see!

BTW, if you want pretty free-form code, why are you using Eval? Just
wondering...

Joe

FieldA is defined as 29.4 and FieldB is defined as 9.0. The following
calculation bombs on "Receiver value too small to hold the result."

Eval FieldB = FieldA;

I know that I can switch back into fixed format and use:
Z-ADD FIeldA FieldB

and the value of FieldB will contain a truncated value if FieldA is too
large to fit in FieldB. However, is there a way to accomplish this in
free-form RPG?

I know that this sounds stupid, and please do NOT ask me why I need to do
this.

I was told that if the value won't fit, truncate it, and I just don't want
to junk up my pretty free-form program with fixed-form code.
