Title: RE: Exponential

You might want to use the Eval(h) ext opcode as well as look into the
expropts(*RESDECPOS) control specification (H-Spec) to respect decimal point sizes.

I'm getting the wrong answer on an eval statement. Why?

Variable definitions:
(I am not using Inz in my program. Only here to give the example some
values)
D#ExPo         S              1P 0   Inz(0)
D#Base         S              4P 2   Inz(18.10)
D#Result       S              5P 2

The Eval statement:
Eval      #Result = #Base + (1 / (10 ** #Expo))

     Expected answer:    19.10
     Actual answer:      19.09

We are on V4R3.

If I break it down, it works.
Eval #CalcExpo = 10 ** (#Expo)
Eval #Result = #Base + (1/#CalcExpo)
